Abstract:
Od osnutka Zavoda i obavljanja rendgenografije svi su rendgenogrami pohranjivani u velikoj prostoriji koja je služila kao filmoteka. Odabirom najinteresantnijih rendgenograma objavljeni su udžbenici: „Opća rendgenologije u veterinarskoj medicini“, „Osteoartropatije u domaćih životinja“ i „Klinička rendgenologija u veterinarskoj medicini“. Koristeći spomenute rendgenske uređaje objavljen je veliki broj stručne i znanstvene literature. Izrađene su i brojne disertacije i magistarske rasprave. Suvremena radiologija sve više koristi digitalne sustave za oslikavanje ljudskog i životinjskog tijela i oni u kliničkoj praksi postupno zamjenjuju analogne uređaje. Digitalna se tehnologija dugo primijenjuje kod kompjutorizirane tomografije (CT), ultrasonografije, magnetske rezonancije (MRI) i nuklearne medicine. Dosadašnja iskustva uglavnom se temelje na analognim podatcima oslikavanja. Instaliranjem Višeslojnog CT skenera (multislice CT scanners) i digitalnom obradom slika kod klasične rendgenografije, Zavod je obogaćen kvalitetnim i višenamjenskim rendgenografskim dijagnostičkim postupcima.

Abstract:
Imunoprofilaksa je umjetno stvaranje imunosti. Provođenje imunoprofilakse vrši se na dva načina, a to su cijepljenje (aktivna imunizacija) i unošenje imunoglobulina (pasivna imunizacija). Aktivna imunizacija ili cijepljenje jest postupak unošenja specifičnog antigena u organizam koji stimulira razvoj specifične obrane prema određenom uzročniku zarazne bolesti. Cijepljenje je dokazano najuspješnija intervencija suvremene medicine i temeljno je ljudsko pravo. Provođenjem cijepljenja u svijetu se znatno smanjio morbiditet i mortalitet u populaciji. U Hrvatskoj se cijepljenje djece i odraslih vrši prema Programu obveznog cijepljenja. Cjepiva se od rođenja primaju u određenim razdobljima života te se neka primaju u jednoj, a neka u više doza. Procijepljenost je u Hrvatskoj na zadovoljavajućoj razini unatoč opadanju postotka procijepljenosti u zadnjih nekoliko godina. Cilj i svrha ovog istraživanja bili su uvidjeti stavove studenata Zdravstvenog veleučilišta (ZVU) o cijepljenju. Uzorak je sadržavao 281 ispitanika. Ispitanici su bili studenti svih smjerova, sve tri godine Zdravstvenog veleučilišta (sanitarno inženjerstvo, sestrinstvo, medicinsko-laboratorijska dijagnostika, radiologija, radna terapija). Rezultati istraživanja pokazali su da svi studenti imaju pozitivan stav o cijepljenju, što je dobar rezultat s obzirom na to da su svi smjerovi zdravstvenog tipa te da im je edukacija o cijepljenju na visokom nivou.

Abstract:
AbstractDuring the 10-year period beginning in 1949 with publication of five articles in two radiology journals and UKs The Lancet, a California radiologist named L.H. Garland almost single-handedly shocked the entire medical and especially the radiologic community. He focused their attention on the fact now known and accepted by all, but at that time not previously recognized and acknowledged only with great reluctance, that a substantial degree of observer error was prevalent in radiologic interpretation. In the more than half-century that followed, Garland’s pioneering work has been affirmed and reaffirmed by numerous researchers. Retrospective studies disclosed then and still disclose today that diagnostic errors in radiologic interpretations of plain radiographic (as well as CT, MR, ultrasound, and radionuclide) images hover in the 30% range, not too dissimilar to the error rates in clinical medicine. Seventy percent of these errors are perceptual in nature, i.e., the radiologist does not “see” the abnormality on the imaging exam, perhaps due to poor conspicuity, satisfaction of search, or simply the “inexplicable psycho-visual phenomena of human perception.” The remainder are cognitive errors: the radiologist sees an abnormality but fails to render a correct diagnoses by attaching the wrong significance to what is seen, perhaps due to inadequate knowledge, or an alliterative or judgmental error. Computer-assisted detection (CAD), a technology that for the past two decades has been utilized primarily in mammographic interpretation, increases sensitivity but at the same time decreases specificity; whether it reduces errors is debatable. Efforts to reduce diagnostic radiological errors continue, but the degree to which they will be successful remains to be determined.

Abstract:
The presence of pulmonary parenchymal cysts on computed tomography (CT) imaging presents a significant diagnostic challenge. The diverse range of possible etiologies can usually be differentiated based on the clinical setting and radiologic features. In fact, the advent of high-resolution CT has facilitated making a diagnosis solely on analysis of CT image patterns, thus averting the need for a biopsy. While it is possible to make a fairly specific diagnosis during early stages of disease evolution by its characteristic radiological presentation, distinct features may progress to temporally converge into relatively nonspecific radiologic presentations sometimes necessitating histological examination to make a diagnosis. The aim of this review study is to provide both the pathologist and the radiologist with an overview of the diseases most commonly associated with cystic lung lesions primarily in adults by illustration and description of pathologic and radiologic features of each entity. Brief descriptions and characteristic radiologic features of the various disease entities are included and illustrative examples are provided for the common majority of them. In this article, we also classify pulmonary cystic disease with an emphasis on the pathophysiology behind cyst formation in an attempt to elucidate the characteristics of similar cystic appearances seen in various disease entities.

Abstract A variety of diffuse diseases affect the calvaria. They may be identified clinically as palpable masses or incidentally in radiologic examinations. The purpose of this study is to illustrate the main diffuse calvarial lesions starting from a case report of fibrous dysplasia of the cranial vault. A 68-year-old male patient who presented with a history of right otalgia and bloody otorrhea was diagnosed to have fibrous dysplasia based on the radiological features. Most diffuse diseases of the calvaria are benign non-neoplastic lesions of unknown origin. The radiologist has a long list of differential diagnosis and their true etiology may be puzzling when the medical evaluation is based only on imaging findings.

Nel 1933 i Professori della Scuola Medica genovese V. Maragliano, GB. Cardinale e A. Vallebona decisero di proporre come Santo Patrono e Protettore dei Radiologi, San Michele Arcangelo. L’iniziativa dei Grandi Maestri genovesi della Radiologia fu accolta subito dai colleghi con grande entusiasmo. Venne quindi inoltrata richiesta scritta di “supplica” a Papa Pio XII per ottenere il riconoscimento ufficiale da parte della Chiesa cattolica. La scelta dell’Arcangelo Michele fu motivata dai Professori in quanto Santo che, nell’iconografia religiosa, è l’unico a vestire l’armatura, è guardiano del Paradiso e conduce le anime a Dio. Inoltre il Santo rappresenta, il trionfo della luce del bene contro le tenebre del male. La Sacra Congregazione dei Riti, emanò in data 15 gennaio 1941 il decreto che costituiva: “Sanctus Michael, Archangelus pro radiologis et radiumtherapeuticis patronus et protector declaratus”.

Abstract:
Chilaiditi syndrome, first described in 1910 by the radiologist Chilaiditi from Vienna, is the interposition of right colon between liver and right hemi diaphragm. It occurs most often in males and its incidence increases with age. It is often detected incidentally during radiological examination. It’s rarely symptomatic; symptoms can differ from mild abdominal pain to severe acute intestinal obstruction. Our case applied to emergency service with right flank pain. There was no calculus or dilatation in the urinary system at non-contrast abdominopelvic computerized tomography. Ascending colon was interposed between liver and diaphragm so that the patient was diagnosed as Chiliaditi syndrome. The patient was treated conservatively and discharged with dietary suggestions by the gastroenterology consultant. The conclusion of this report is that the Chilaiditi syndrome must be considered in differential diagnosis for patients presenting with urinary colic pain symptoms with no urinary pathology on radiologic imaging.

Abstract:
Radiological diagnosis of systemic mastocytosis (SM) can be hard to establish. This is mainly due to the variable radiological features involving many organ systems (e.g., respiratory, cardiovascular, lympho-reticular, digestive systems, and most commonly skin), and the broad spectrum of skeletal findings, in particular. Skeletal involvement is the most common and prominent imaging feature in patients with SM and represents a prognostic factor as it may entail an aggressive course of the disease. Diagnosis, which is largely established by histological evaluation of a bone marrow trephine biopsy specimen supplemented by imaging modalities such as radiography, CT, and magnetic resonance imaging, requires a team approach between the hematologist, radiologist, and pathologist. The general radiologist needs to be familiar with the imaging findings because they may be the first to suggest the correct diagnosis. The primary purposes of this article were to equip clinicians with pertinent radiological semiotics and present relevant radiological features that assist early diagnosis and selection of an effective treatment.

Abstract:
Background Due to their crucial role in many diagnostic processes, a considerable number of papers in non-radiological medical journals contain images. We noticed that radiologists are seldom mentioned as co-authors. Purpose To investigate how often radiologists are involved as co-authors and to measure the influence of their involvement on the choice and quality of the illustrations and captions. Material and Methods We queried PubMed for papers in English with the search string “case report” in the title, examined them for the presence of radiological images, and excluded those published in radiological journals. We developed a scoring system, containing objective and subjective qualification criteria. In addition, we checked if a radiologist was involved as co-author, or mentioned in the Acknowledgments section. We performed a statistical analysis to check if the involvement of a radiologist had a significant effect on the overall quality of the case report. Results In 21% (45/218) of the papers, a radiologist was mentioned as co-author and in 3% (7/218) a radiologist was mentioned in the acknowledgments. In 76% (166/218), radiologists were neither involved as co-authors, nor mentioned in acknowledgments. We found statistically significant quality differences between these three groups ( P < 0.001). Conclusion This study indicated that the quality of case reports can be improved when radiologists are involved in the preparation and publication of papers containing imaging studies.

Abstract:
With an aging and growing population, the number of women receiving mammograms is increasing. However, existing techniques for autonomous diagnosis do not surpass a well-trained radiologist. Therefore, to reduce the number of mammograms that require examination by a radiologist, subject to preserving the diagnostic accuracy observed in current clinical practice, we develop Man and Machine Mammography Oracle (MAMMO)—a clinical decision support system capable of determining whether its predicted diagnoses require further radiologist examination. We first introduce a novel multi-view convolutional neural network (CNN) trained using multi-task learning (MTL) to diagnose mammograms and predict the radiological assessments known to be associated with cancer. MTL improves diagnostic performance and triage efficiency while providing an additional layer of model interpretability. Furthermore, we introduce a novel triage network that takes as input the radiological assessment and diagnostic predictions of the multi-view CNN and determines whether the radiologist or CNN will most likely provide the correct diagnosis. Results obtained on a dataset of over 7,000 patients show that MAMMO reduced the number of diagnostic mammograms requiring radiologist reading by 42.8% while improving the overall diagnostic accuracy in comparison to readings done by radiologists alone.

Introduction:In 2013, a multinational collaboration met to improve the global and nation-specific preparedness and response in managing casualties from nuclear and radiological disasters. From this meeting, a survey was developed and distributed in both Japanese and English. The results published four years later illustrate a lack of understanding about radiation and risks to the health care provider.Aim:To dispel myths and increase understanding regarding trauma treatment and healthcare risks for healthcare providers during a radiologic event.Methods:IRB approved survey and literature reviewResults:A total of 418 surveys were analyzed. Although 44% of participants acknowledged that they had taken at least one radiological training course, the majority of the respondents were still not comfortable with radiological emergencies.Discussion:Despite the plethora of both online and in-person radiological training availability, healthcare providers are not comfortable with the topic. Based on information from the survey, it is important to dispel myths and educate healthcare providers so that they have reasonable expectations regarding risks and to ensure that they are comfortable coming to work. By doing this, there will be an adequate healthcare presence to help take care of patients who are not only in need of immediate trauma and radiologic exposure care but also with non-affected patients coming for emergent and scheduled health care needs.

Fibrofatty bands are composed of adipose tissue and connective tissue and can tangle around the bowel and caused intestinal obstruction. Currently, there is a lack of radiological teaching or guidance on how to identify fibrofatty band in patients with bowel obstruction. The true incidence of fibrofatty band-induced bowel obstruction is likely to have been overlooked. We present a case series of patients with fibrofatty bands with different features and aim to highlight the key radiological findings that may help in the radiological diagnosis. We advocate that these features should be incorporated into the current algorithm for radiologist when assessing scan images of patients with intestinal obstruction.

AbstractCortical microinfarcts (CMI) are increasingly recognized in the neurological community as a biomarker related to cognitive impairment and dementia. If their radiological depiction has been largely described in experimental settings using ultra-high-field magnetic resonance imaging (MRI), less is known about their visibility on routinely used 3-T MRI. In this radiologic-pathologic correlation study, using 3-T post-mortem MRI, we searched for hippocampal CMI, in a double-blinded fashion, and found that only 4/36, or 11%, were clearly demonstrated on both radiological and histopathological exams.

Abstract:
The radiation dose to patients and personnel was estimated during 11 percutaneous renal stone extractions. For the patients the energy imparted, the mean absorbed dose to various organs, and the effective dose equivalent were estimated. For different personnel categories some organ doses and the effective dose equivalent were also estimated. Large differences in the radiation dose between patients were observed. The mean effective dose equivalent to the patient was 4.2 (range 0.6–8.3) mSv, and the energy imparted 285 (range 50–500) mJ. These figures are comparable to those reported for routine colon examination and urography. For the personnel there were also large differences between individuals and categories. The highest radiation dose was received by the radiologist. It was estimated that a radiologist who performs 150 percutaneous renal stone extractions per year will receive a yearly contribution to his/her effective dose equivalent of 2.4 mSv. Even when the contribution from other diagnostic and interventional radiologic procedures is added, the total effective dose equivalent hardly exceeds 5 mSv or 1/10 of the present dose limit for persons engaged in radiologic work. For the hands of the radiologist there is a risk of doses closer to the present limit for single organs or tissues of 500 mSv/year.

Abstract:
English is considered to be difficult due its different natures with Bahasa Indonesia both in pronouncing and writing. However, English textbooks are widely used in many program studies including in radiology. Therefore, many students have difficulties in understanding and comprehending the books due to their limited English ability especially related to English vocabularies and grammatical. This study aimed to acknowledge lexically and syntactically the linguistics features used in the textbook of Radiographic Positioning and Related Anatomy, which is a must-read book used during the study in the study program of Radiology. The method applied in this Corpus Linguistic study was a combination of quantitative method by using a concordancer called AntConc to analyze the radiology book quntitatively to get the word frequency list, and qualitative method in analyzing the quantitative data to describe the language features used in the textbook. The results of the quantitative and qualitative analyses show the most common vocabularies, word classes, and sentence patterns used in the text book that will be used to compose a pocket dictionary, which will help the radiography students to understand the radiological terms and comprehend many radiological sources autonomously and easily. Furthermore, through the dictionary, the students will not only be able to understand and comprehend many radiological texts but they will also be able to write texts and even discuss radiological topics in English autonomously. Results of the study show that AntConc has benefited the researchers since it has been able to assist the researchers in providing needed lexical and syntactical information of the textbook.  Bahasa Inggris dianggap sulit karena berbeda dengan bahasa Indonesia baik dalam pengucapan maupun penulisannya. Walaupun demikian, di Indonesia buku-buku teks berbahasa Inggris banyak digunakan di berbagai program studi termasuk di bidang radiologi. Oleh karena itu, banyak mahasiswa mendapatkan kesulitan untuk mengerti dan memahami buku-buku berbahasa Inggris tersebut karena keterbatasan pengetahuan Bahasa Inggris mereka terutama berkaitan dengan kosakata dan gramatika bahasa Inggris. Penelitian ini bertujuan untuk mengetahui fitur linguistik dalam bentuk kosakata dan gramatika yang digunakan dalam buku Radiographic Positioning and Related Anatomy. Buku ini merupakan buku yang wajib dipelajari mahasiswa di Program Studi Radiologi. Penelitian ini menggunakan metode gabungan antara kuantitatif dan kualitatif. Dengan menggunakan perangkat lunak konkordansi AntConc data dianalisis secara kuantitaif untuk mendapatkan daftar kata berdasarkan kekerapannya. Selanjutnya, metode kualitatif diaplikasikan untuk menganalisis dan menjelaskan data yang dihasilkan. Analisis kuantitatif dan kualitatif tersebut menghasilkan daftar kosakata, kelas kata, dan pola kalimat yang sering muncul dan akan digunakan untuk menyusun kamus mini buku tersebut. Keberadaan kamus ini diharapkan dapat membantu mahasiswa radiologi untuk memahami terminologi radiologi dan memahami banyak teks radiologi secara mandiri dengan mudah. Lebih lanjut lagi, mahasiswa tidak hanya mampu memahami banyak teks radiologi tetapi juga mampu memproduksi teks, bahkan berdiskusi tentang radigrafi dalam bahasa Inggris secara madiri. Hasil penelitian menunjukkan perangkat AntCont telah memberikan manfaat kepada peneliti karena perangkat ini telah mampu membantu peneliti untuk mempersiapkan informasi leksikal dan gramatikal bahasa Inggris yang terdapat pada buku radiologi di atas.

Abstract:
Diagnostic radiology should assume a more prominent role in medical student education. We have developed a 4-year plan for radiologic education at the University of Florida. The initial step in this plan is a required credit course in radiologic anatomy given in the first semester. Designed to introduce students to various imaging modalities while teaching anatomic recognition, the course combines a lecture series with systematized self-study film packets and self-test packets. These are reinforced by a videotape series and other written materials. Examinations are in practical format utilizing radiographs on viewbox stations. The course provides a foundation for subsequent coursework in diagnostic radiology, including radiologic pathology and clinical radiology. These courses stress how to workup patients and how to use the radiologist as a consultant in patient care. The response to the radiologic anatomy course has been highly favorable.

Abstract:
361 Background: Prognosis and tumor responses of carboplatin-based neoadjuvant chemotherapy for muscle invasive bladder cancer (MIBC) are not well documented. To assess the usefulness of carboplatin-based neoadjuvant chemotherapy, we examined the correlation between radiological responses and pathologic down staging on radical cystectomy (RCx) specimens, disease free survival (DFS), and overall survival (OS). Methods: Between March 2005 and June 2013, we performed carboplatin-based neoadjuvant chemotherapy followed by radical cystectomy in 115 patients with T2-4NxM0 MIBC. After diagnostic TUR biopsy, all participants received two courses of Gemcitabine plus Carboplatin therapy. Baseline and post chemotherapy tumor size from contrast enhanced CT were reviewed. The patients were divided in two groups between responders (CR+PR), and non-responders (SD+PD). RCx and bilateral pelvic lymphadenectomy were performed approximately within a month after cessation of chemotherapy. DFS and OS distributions within radiologic response subgroups were estimated with the Kaplan-Meier method and compared using the log-rank test. To evaluate independent predictor for DFS and OS, age, gender, performance status, pathological T and N stage, down-staging, tumor grade, renal function, and radiological responses were applied by Cox-regression multivariate analysis. Results: No significant differences were observed in patient backgrounds between the groups. Radiologic responses were observed in 75 (65%) patients with 69±24% decrease in responder group, whereas tumor response was 2.8±14% in non-responders. The rate of pathological down staging to <pT2 was 37 (49%) in responders, 5 (13%) in non-responders group. Radiologic response was a strong predictor of DFS and OS. A 5-year advantages of DFS and OS in responders vs. non-responders were 88% and 86% vs. 64% and 69%, respectively (P=0.021 and P=0.013). Multivariate analysis showed radiologic response was the independent factor for DFS and OS. Conclusions: Radiological response post carboplatin-based neoadjuvant chemotherapy is associated with OS in patients with MIBC.

Objective.To assess the importance of natural language processing (NLP) system for quality assurance of the radiological reports.Material and methods.Multilateral analysis of chest low-dose computed tomography (LDCT) reports based on a commercially available cognitive NLP system was performed. The applicability of artificial intelligence for discrepancy identification in the report body and conclusion (quantitative analysis) and radiologist adherence to the Lung-RADS guidelines (qualitative analysis) was evaluated.Results.Quantitative analysis: in the 8.3% of cases LDCT reports contained discrepancies between text body and conclusion, i.e., lung nodule described only in body or conclusion. It carries potential risks and should be taken into account when performing a radiological study audit. Qualitative analysis: for the Lung-RADS 3 nodules, the recommended principles of patient management were used in 46%, for Lung-RADS 4A – in 42%, and for Lung-RADS 4B – in 49% of cases.Conclusion.The consistency of NLP system within the framework of radiological study audit was 95–96%. The system is applicable for the radiological study audit, i.e. large-scale automated analysis of radiological reports and other medical documents.

The contemporary radiologist has been catapulted to the forefront in the management of adrenal disease. With the increasing use of cross-sectional imaging, adrenal lesions are being serendipitously discovered in radiological studies undertaken for non-adrenal-related conditions – the so-called adrenal ‘incidentaloma’. This review discusses the imaging modalities available for characterising these lesions, highlighting current concepts and controversies in differentiating benign from malignant pathology. The article also provides a brief overview of the spectrum of adrenal pathology commonly encountered in the adult population.

Abstract:
Aim: To highlight radiological features and emphasize the need for tissue diagnoses to confirm bone pathology. Tuberculosis is known to present without constitutional symptoms and with unconventional imaging features mimicking sarcomas as shown in our series of 25 patients; where the imaging and biopsy protocols at our institute helped to solve these diagnostic dilemmas. Material and methods: We retrospectively analyzed clinical and radiological features and tissue diagnoses in 25 patients referred to the department of orthopedic oncology with radiological suspicion of tumor. Results: Only 7 patients had cultures positive for Mycobacterium Tuberculosis T.B. Radiological features suggestive of infection were Metaphyseal and joint involvement, permeative lesions, absence of Codman’s triangle, and soft tissue mass suggestive of a cold abscess. The predictive accuracy of the orthopedic oncologist was 60% and musculoskeletal radiologist was 72% (based on radiology). Final diagnosis is 100% confirmed on histopathology. Conclusion: Diagnosis based primarily upon imaging is a wrong approach. A multimodal approach to differentiating tuberculous bone infections from sarcomas is essential.

Abstract:
Introduction. The systemic autoimmune diseases (SAD) can cause a variety of pulmonary and pleural abnormalities. The aim of this paper is to review clinical and radiological characteristics of a series of patients with a systemic autoimmune disease hospitalized at a tertiary level facility. Methods. In this retrospective study, we reviewed the clinical and imaging findings in patients diagnosed with SAD at the Teaching Hospital of Pulmonology during a nine-year period. Results. An 84-patient group (mean age of 53.8 years) consisted of 64 women and 20 men. Fifty-eight out of 84 patients suffered from collagen vascular disease (CVD) and 26/84 had systemic vasculitis. Fatigue was the dominant symptom (75.8% in CVD, and 69.2% in vasculitis). Cough, hemoptysis, and fever were more frequent in patients with vasculitis. Fibrosis was the most common radiological manifestation of CVD (26/58), followed by pleural effusion (18/58) and consolidation (10/58). Irregular opacities were dominant radiologic finding in vasculitis (10/26), followed by nodules (8/26). Histological confirmation of systemic autoimmune disease was obtained in 28.6% patients, in 58/84 patients the diagnosis was based on a positive serologic test and clinico-radiological manifestations, in two cases on clinical and radiological features according to defined criteria. Conclusion. Pleuropulmonary manifestations of SAD are usually expressed in the sixth decade of life, predominantly in women. Clinical findings and positive serologic tests suggest diagnosis of SAD. Fibrosis is the most common radiologic pattern found in almost one half of the patients with CVD and irregular opacities are the most common findings in vasculitis.

Abstract:
Background. Clinical, laboratory, and radiologic parameters are used for diagnosis and classification of spondyloarthritis (SpA). Magnetic resonance imaging (MRI) of sacroiliac (SI) joints is being increasingly used to detect early sacroiliitis. We decided to evaluate the interobserver agreement in MRI findings of SI joints of SpA patients between a local radiologist, a rheumatologist, and an expert radiologist in musculoskeletal diseases. Methods. 66 MRI images of the SI joints of patients with established diagnosis of SpA were evaluated. Agreement was expressed in Cohen’s kappa. Results. Interobserver agreement between a local radiologist and an expert radiologist was fair (κ=0.37). Only acute findings showed a moderate agreement (κ=0.45), while chronic findings revealed 76.5% of disagreement (κ=0.31). A fair agreement was observed in acute findings (κ=0.38) as well as chronic findings (κ=0.38) between a local radiologist and a rheumatologist. There was a substantial agreement between an expert radiologist and a rheumatologist (κ=0.73). In acute findings, a 100% agreement was achieved. Also chronic and acute plus chronic findings showed high levels of agreement (κ=0.73 and 0.62, resp.). Conclusions. Our study shows that rheumatologists may have similar MRI interpretations of SI joints in SpA patients as an expert radiologist.

Computed tomography (CT) of chest organs is one of the most accurate diagnostic methods allowing the physician to assess the condition of lung parenchyma. Correct interpretation of CT results requires the clinician to recognize normal appearance of lung parenchyma on X-ray and know changes visualized in various bronchopulmonary diseases. It is important that the physician knows and understands underlying cause of a particular radiological pattern in order to discuss with the radiologist lung tissue changes that have been identified considering clinical symptoms. Descriptions of radiological patterns and discussion of corresponding typical clinical observations are presented in the article devoted to air cyst syndrome and cystoid changes in the lung tissue.

Abstract:
A wireless hand-held Webpad device was used to review a sample set of cranial computerized tomography (CT) studies to assess its diagnostic capabilities and its feasibility as a portable diagnostic workstation for radiology. The data-set consisted of 30 head CT studies of emergency cases. Two neuroradiologists and a senior radiologist participated in the evaluation of the portable workstation. They used a Web-based viewer that we developed, which provided all the major functionalities required for radiological image review. The reported radiological findings and diagnoses were compared with a gold standard, comprising a set of diagnoses previously formulated by a consensus panel of radiologists who had reviewed the original studies. The diagnoses made using the Webpad were correct (no major discrepancies) in 82 out of 90 interpretations (91%), which is comparable to the accuracy reported in image review with a conventional radiological workstation. The average total working time per diagnosis was 5 min 25 s (range 2–12 min). The simplicity of use of the system and its low cost make it suitable for distributing radiological studies within hospital facilities.

Abstract:
AbstractThis paper focuses on the legal implications in terms of duties and responsibilities for radiologists and radiologic technologists of independent pre-reading of mammograms by radiologic technologists, so patients could be discharged without being seen by a radiologist. Pre-reading could be effectuated when preconditions are met to perform reserved procedures by unauthorised professionals as stated in the Individual Health Care Professions (IHCP) Act. Furthermore, compliance with a protocol or code of conduct in combination with adequate training and supervision should be sufficient to disprove potential claims. For a wide implementation, pre-reading should be well-embedded in legal rules and should answer the professional standard of care.

Abstract:
Objective.To describe the longterm clinical and radiological outcomes in rheumatoid arthritis (RA) in a cohort in northwestern Greece; and to investigate predictive factors of radiological damage at the 10-year followup in patients with RA.Methods.We studied the disease course and outcome of 144 patients with RA and radiographs of the hands and wrists available at baseline and at 10 years. Baseline measurements and time-averaged measures of swollen joint count (SJC) and inflammatory markers [erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP)] were tested in univariate analysis, and then those presenting a statistically significant association with either Larsen score at 10 years or annual progression rate were included in 2 logistic regression models in order to determine relevant independent prognostic factors.Results.A significant clinical improvement was noted, associated with a decrease of inflammatory markers along the timepoints. Larsen score and the number of erosive joints were increased. In the univariate analysis, both final Larsen score at 10 years and accelerated annual radiological progression rate were significantly associated with baseline radiographic measurements (Larsen score and number of erosive joints), the presence of autoantibodies [anticyclic citrullinated peptide antibodies (anti-CCP) and rheumatoid factor of IgA and IgM isotype], disease duration, and time-averaged measures of ESR, CRP, and SJC. In the logistic regression analysis, the baseline Larsen score, anti-CCP antibodies, and time-averaged CRP presented significant and independent associations with Larsen score at 10 years. An accelerated annual radiological progression rate was also predicted by baseline Larsen score and time-averaged measures of SJC and CRP.Conclusion.Despite clinical improvement, the radiologic progression of RA continues over time, because of the underlying inflammatory process. Baseline radiographic damage, anti-CCP antibodies, and time-averaged CRP constitute the main predictive factors of poor radiologic outcome in the long term.

Abstract:
La diagnosi di instabilità del rachide lombo-sacrale è, a tutt'oggi, fondamentalmente clinica. Anche le più sofisticate tecniche di diagnostica radiologica consentono infatti solo una valutazione statica di questa entità nosologica (che, per definizione si manifesta durante la deambulazione e con la stazione eretta) la cui definizione dinamica è campo pressochè esclusivo della radiologia convenzionale. Presentiamo i risultati di uno studio condotto attraverso l'uso di uno strumento originale progettato per sviluppare un carico assiale variabile e riproducibile in un paziente supino: il Compressore assiale. Con questo strumento, compatibile con l'esecuzione di esami TC, sono stati valutati 24 pazienti con forte sospetto clinico-radiologico di instabilità lombare. La metodica di studio, denominata Axial Loaded - Computed Tomography (AL-CT) si basa sull'acquisizione successiva di esami TC basali e con carico assiale (AL), che vengono poi comparati. Il confronto avviene sia sulle scansioni assiali che su immagini ricostruite su piani sagittali e con «rendering» tridimensionale (3D-TC). La valutazione comparativa prevede sia l'uso di immagini statiche che l'organizzazione in sequenze cine (cine AL-CT) delle immagini 2D e 3D ottenute. Tutti i procedimenti di rielaborazione sono indispensabili nella valutazione dei risultati. I risultati mostrano con chiarezza reperti (numerosi e spesso simultanei) a carico di tutte le component le unità funzionali spinali; fra questi meritano una segnalazione: l'incremento o la accentuazione di protrusioni discali sotto carico; la scomparsa del vacuum discale e/o intraarticolare durante la compressione («segno del vacuum»); l'accentuazione della listesi sotto carico; la ottimale ed originale visualizzazione dell' ipermobilità delle faccette articolari. Proponiamo AL-CT e cine AL-CT come metodiche di scelta nello studio dell'instabilità lombare.

Abstract:
Dermatomyositis – a systemic connective tissue disease, from the group of idiopathic inflammatory myopathies. Affection of the skeletal muscle tissue in inflammatory myopathies causes progressive muscle weakness. In dermatomyositis reduction in contraction ability of the muscles involved in the act of swallowing, leads to violation of the mechanism of respiratory protection from getting food masses inside and from development of dysphagia.The purpose of the study was to evaluate the changes detected in the process of radiologic examination of the dermatomyositis patient’s throat.Materials and methods. Patient K. 61 years old, he has dermatomyositis and clinical signs of oropharyngeal dysphagia. The patient underwent a pharyngeal radiologic examination, which allowed to confirm the disturbance of swallowing function and to establish the fact of aspiration.Results and discussion. Radiological examination of the pharynx showed signs of pharynx hypotony, pharyngeal ectasia, stasis, residual amount of radiocontrast agent in caudal section of larynx, penetration, aspiration.Conclusion. Radiological examination of the pharynx in patients with dermatomyositis is important method examination of studying swallowing disorders and predicting risk of serve complications.The peculiarity of this case is the demonstration of swallowing dysfunction dynamics in a patient with dermatomyositis at admission to the clinic and after treatment.

Abstract:
In recent years, an important part of the ionizing radiation (IR) that human have been exposed for diagnostic purposes are interventional radiologic procedures. The X-rays and contrast media are used in angiography. The patients and staff members are exposed to X-ray during these procedures. While it is known that X-rays cause DNA damage and carcinogenesis, the effect of the contrast agent is still unknown. The aim of this study was to investigate the effect of X-rays and contrast agent on chromosomes of human patients. Peripheral blood samples were taken from 50 patients (30 males, 20 females, ages between 38-75 years). Chromosome analysis of peripheral lymphocytes in 50 patients were performed at 3 different periods; before the interventional radiologic procedure, 24 hours and 1-3 months after the procedure. Also, chromosome analysis was performed on 17 staff members working during interventional radiological procedures to investigate the effect of X-rays. Standard cytogenetic analysis techniques were used for this study. The frequency of chromosomal aberrations (CAs) was significantly higher in patients 24 hours after the interventional radiologic procedures than pretreatment (p=0,000). At the same time, CAs after 24 hours compared with those taken 1-3 months later, shown that the CAs were significantly reduced after 1-3 months (p=0,000). We also found that the frequency of CAs was also statistically higher in patients exposed to high radiation doses (p=0,042). Compared with the control group (n=30), CAs were found significantly higher in workers exposed to radiation. Our findings have shown that X-rays and contrast agents that used in interventional radiological cause chromosomal damage. For this reason, the dose of radiation to be given to the patient must be carefully selected. Due to the potentially high genetic damage of patients with coronary artery disease (CAD), the type and amount of medication to be given and the frequency of radiological diagnostic procedures to be performed should be meticulously adjusted.
