Abstract:

All chest radiographs of 107 proven lung cancer patients who received consecutive biennial chest radiography were reviewed to elucidate problems detecting their cancers, and diagnosing them when initially radiographically detected. Subjects, members of a fixed population sample, originally numbered 20000 persons, 17000 of whom consistently received consecutive biennial chest radiography during examinations for late effects of atomic-bomb radiation. Among the 107 subjects, 64 had radiographic manifestations of cancer; 47 were initially correctly diagnosed; 17 were not. Eleven of the 17 were initially equivocal, diagnosable only after subsequent radiography and retrospective review of serial radiographs. Diagnostic problems consisted of 1) six detection errors with cancer images superimposed on musculoskeletal and cardiovascular structures, reducible by stereoscopic p.a. instead of single p.a. radiography; immediate tentative interpretations; and by comparing earlier with current radiographs. 2) Eight decision errors, wherein cancers mimicked other diseases, were reducible by greater index of suspicion and scrutiny during interpretations.

Abstract:

The aim of this study was to compare the effectiveness of in-vitro methods for the occlusal dentine caries diagnosis. Thirty-eight sites were evaluated on third molars without macroscopic carious cavitation in adult individuals from the city of Barretos (SP), Brazil. Visual inspection (VI), endoscopic evaluation (AcuCam), visual inspection and blunt-tipped exploratory probes (Tactile), conventional bite-wing radiographs (CR), direct bite-wing digital radiograph (DR), and direct digital radiograph with contrast and brightness controled (DRbc) were used by five observers. In order to validate the data, the teeth were sectioned and histologically evaluated. The average sensitivity and specificity values of the methods were respectively:0,25 , 0,96 (VI); 0,15 , 0,92 (AcuCam); 0,17 , 0,95 (Tactile); 0,45 , 0,73 (CR); 0,33 , 0,80 (DR) and 0,35 , 0,84 (DRbc) , the effectiveness of clinical methods (VI, AcuCam and Tactile) as well as that of radiographic methods (CR, DR and DRbc) were comparatively similar. The clinical methods presented a smaller number of false-positive diagnosis than the radiographic methods. It was concluded that visual inspection is an important diagnostic method; conventional bite-wing and digital radiography aid the diagnosis and are equally efficient to diagnose carious lesions in the dentine of teeth without visible cavitation.

Abstract:

Aim: The aim of the present study was to compare and assess the relationship and agreement between the clinical and radiographic detection of Furcation Involvement (FI) in the mandibular molars of patients with periodontitis. Materials and Methods: The sample size included 360 molars from 283 participants with a total of 180 molars involved with furcation clinically and 180 without. The inclusion criteria involved records of patients in the age range 35-76 years, diagnosed with generalized periodontitis, Stage II to IV, Grade B and C, and existing periapical radiographs/dental panoramic radiographs. The periodontal charts (Hamp’s classification) and radiographs were used to evaluate furcation on the buccal and lingual sites of first and second mandibular molars. Results: Of the 360 molars, half of the molars (50%, n=180) had clinical FI. Of the clinical FI group, the majority (73%, n=131) demonstrated FI in the radiological assessment with the periapical radiographs. In the not-clinically detected FI group, just less than half (49%, n=89) demonstrated FI in the radiological assessment. The sensitivity of the radiographic detection of FI as a diagnostic marker was 50.6%, and the specificity was 72.8%. Of the 180 sites analyzed with FI clinically, a slight agreement was found between the clinical assessment and radiographic findings using the kappa analysis (k=0.18). The first mandibular molars showed a fair agreement (k= 0.21) compared to the second mandibular molars (k=0.15). In terms of the individual sites, the lingual sites (k=0.24) had a fair agreement compared to the buccal sites with a slight agreement. The Spearman Correlation analysis for the first mandibular molar showed a moderate positive correlation (r=0.4, p<0.001) compared to the second mandibular molar with no or negligible relationship (r=0.19, p<0.001). Comparatively, the DPT radiograph showed a weak correlation and poor agreement. Conclusion: Both diagnostic tools, intraoral radiography and clinical assessment should be used for diagnosing FI in mandibular molars.

Abstract:

Within a century, dental radiology “suffered” transformation, beginning with periapical radiographs, cephalograms and panoramic radiography and continuing with digital imaging and cone beam computed tomography. In contemporary dental practice is importantant to choose the type of radiographic investigation in order to achieve a complete and accurate diagnosis, so necessary for determining the treatment plan for patients with dental-maxillary abnormalities. We conducted a comparative study between conventional radiographic investigation (periapical radiographs, panoramic radiography) and cone beam computed tomography in patients with malocclusions. The costs and radiation doses are low to the classic X-rays, but the diagnosis is given by the two-dimensional image of a three-dimensional dental-maxillary pathologies. Cone Beam CT scans were relatively high in cost and in radiation doses, but provided three-dimensional images and anatomic and radiological data of superior quality to the classics.

Abstract:

There is a high incidence of bronchitis and asthma cases in veterinary medicine. Thoracic radiographs and bronchoalveolar lavage (BAL) are commonly performed for definitive diagnosis in dogs and cats with suspected bronchitis and asthma. It is believed that a combination of diagnostic tools is the best choice to achieve a diagnosis. The aim of this study was to evaluate the efficacy of thoracic radiographs and BAL in the diagnosis of chronic bronchial disease (CBD) in dogs and cats and whether there is any specific radiographic finding that could influence the indication for bronchoalveolar lavage. It was performed a cross-sectional, prospective, observational study including forty client-owned dogs and cats with lower respiratory tract signs and positive radiographic opacities that were evaluated with BAL followed by cytology and culture. The radiographic results compared with BAL culture showed a sensitivity of 38%, specificity of 95% and accuracy of 65% in detecting patients with pneumonia associated with chronic bronchial disease. Thoracic radiographs were effective in diagnosing 65% of the patients, radiographs plus BAL cytology diagnosed 75% of patients and the combination of radiographs, BAL cytology and culture diagnosed 95% of the patients with chronic bronchial disease. In conclusion, the combination of radiographic examination with BAL followed by cytological and microbiological analyses increases diagnostic success in CBD.

Abstract:

For many years, radiographs have been a valuable aid in the diagnosis of periodontal disease and the evaluation of treatment effects. Computer-based image acquisition and processing techniques will now further increase the importance of radiography in periodontal diagnosis. Temporal changes of lesions can be made easily visible by means of subtraction radiography based on digital images. This process requires a pair of images with identical gray-level distributions and projection geometry. The gray-level distribution and perspective projection of images can be corrected by means of digital image processing. A pair of identical images can thus be obtained without mechanical alignment of patient, film, and x-ray source. Algorithms have been developed for automatical determination of the borders of lesions and can subsequently produce quantitative information ranging from simple distance measurements to advanced multidimensional quantitation of image parameters. Accurate volume measurements can be carried out by the utilization of calibration wedges in the image. Image reconstruction procedures, such as tomosynthesis, provide information about the third dimension, which is normally lost in conventional radiographic projections. The buccal and lingual sites of the alveolar crest can be inspected separately. The progress of computer-aided procedures as discussed in this paper appears to have great potential for the improvement of the radiographic diagnosis of periodontal lesions. Especially, the benefits of reproducibility and quantitative evaluation of treatment effects will greatly improve the role of radiography in periodontics.

Abstract:

Background: The accurate measurement of flatfoot on standing radiographs allows correct diagnosis of the condition and evaluation of reconstructive procedures. Method: The standing radiographic measurements of patients with symptomatic, adult flatfoot were compared to controls using blinded observers. Results: On the lateral radiograph, the talar-to-first metatarsal angle, the calcaneal pitch angle, and the medial cuneiform-fifth metatarsal height differed significantly between the patient group and the controls. The difference in the talar-to-first metatarsal angles on lateral radiographs was the most statistically significant (patient group 21.1 ±10.8 degrees and control 7.1 ± 10.7 degrees, p < 0.0001) with good correlation between readings (intraobserver 0.75, interobserver 0.83). On the anteroposterior (AP) radiograph, the talar head uncoverage distance was the most significantly different measurement between these groups. Conclusions: These findings support the hypothesis that the talar-first metatarsal angle is an accurate radiographic identifier of patients with symptomatic, adult flatfoot.

Abstract:

Summary Objective: Medial coronoid disease (MCD) is a very common form of elbow joint disease and it’s radiographic diagnosis can be challenging since it is frequently based on the detection of rather subtle primary or secondary changes than on a large primary lesion. We hypothesized that accuracy of radiographic diagnosis of MCD is highly dependent on training and experience level. Methods: Radiographs of 102 canine elbows were evaluated for MCD by four observers with different levels of training and experience. All elbows underwent CT scans and arthroscopy. Sensitivity and specificity of radiographic and CT interpretation was determined using arthroscopy as a gold standard. Interobserver and intraobserver agreement (reliability and repeatability) were assessed by using Cohen’s Kappa (κ) statistic. Results: The sensitivity (92.4–96.7%) of the two experienced observers was almost comparable to that of CT (100%) and significantly higher than that of the two less experienced observers (77.2–80.4%). Reliability of the radiographic diagnosis of MCD was better between observers with higher experience level (κ = 0.74) than between observers of lower or different experience levels (κ =0.07–0.42). Repeatability was better in experienced (κ = 0.73–0.88) than in less experienced observers (κ = 0.31–0.42). Conclusion: Our results confirm that training and experience play important roles in reaching high sensitivity, reliability and repeatability for the radiographic diagnosis of MCD. Clinical relevance: Although radiography is inferior to CT in imaging of the medial coronoid process itself, sensitivity of radiographic diagnosis MCD can be significantly improved with observer experience almost reaching that of CT. Therefore, it is advised that radiographic screening for MCD should be performed by specialists experienced in the radiographic evaluation of elbow joint disease.

Abstract:

Background: To evaluate chest radiographic patterns in neonatal respiratory distress using a predesigned performa and algorithm and to correlate results with the clinical diagnosis.Methods: A retrospective review was done of bedside chest radiographs acquired over a month for respiratory distress from the neonatal intensive care unit. The radiographs were systematically evaluated according to a predesigned performa and algorithm. A presumptive radiographic diagnosis was assigned to each patient based on the combination of radiographic features. Radiographic diagnosis was compared with the clinical diagnosis. The most important diagnostic features were outlined.Results: The radiographic diagnosis correlated with clinical diagnosis in 93.3% of cases. Most common radiographic feature was pulmonary air space opacity (n=21). Air space opacity without any mediastinal shift in absence of any compensatory factors was a reliable diagnostic feature for pneumonic consolidation, which was the most common diagnosis (n=10). Bilateral granular lung fields were a specific indicator of respiratory distress syndrome. Flattening of domes of diaphragm was the most frequent feature for hyperinflation. Bilateral hyperinflation could be accurately used to diagnose bronchiolitis in all but one case (n=4/5). Pleural complications were accurately diagnosed.Conclusions: Systematic evaluation of neonatal chest radiographic patterns of disease has a high diagnostic accuracy.

Abstract:

Objectives: Aspirated objects generally represent items accessible to children. When metallic candy wrapper aspiration is questioned, radiographic studies may aid diagnosis. An infant with repeated chest radiographs negative for a metallic foreign body was found to have a multi-layer metallic candy wrapper in the left main bronchus. The purpose of this study was to determine whether conventional and dual-energy radiographic techniques exclude the presence of aspirated metallic foil wrappers. Methods: Single-layer and multi-layer metallic candy wrappers were radiographically studied with conventional and dual-energy radiographic techniques in 3 tissue models. Results: No single-layer metallic samples were detectable with conventional or dual-energy radiography. The multi-layer samples were not detectable at less than 8 layers (pulmonary tissue model) or 16 layers (mediastinal model) by either conventional or dual-energy radiography. Conclusions: Conventional and dual-energy chest radiographic techniques do not reliably exclude the presence of aspirated metallic foil wrappers.

Abstract:

Objectives: The aim of this case report is to provide further information on the radiological features of a solid type ameloblastoma suspected on a 3D CBCT radiograph. Case Report: A patient came referred by a dentist for CBCT 3D radiography with suspected clinical diagnosis of a maxillary anterior dentigerous cyst. The results of the CBCT 3D radiographic examination showed a radiointermediate with a clear border on the anterior maxilla and in the right maxillary sinus accompanied by the impact of two supernumerary teeth. Radiological features of ameloblastoma generally show a multilocular radiolucent picture and have a radiopaque septa bone internal structure such as a soap bubble appearance or honey combed appearance. This case showed a clearly demarcated radiointermediate image because a solid type ameloblastoma contains tissue that is histologically formed from cells hat are follicular or plexiform and derived from the results of a degenerative process at the center of the Langerhans islands.  Conclusion: Radiographic examination with high modality such as CBCT 3D is very important in helping to establish a diagnosis, especially for cases that sometimes show differences in the radiographs.

Abstract:

This prospective cohort study investigated the distribution pattern of carious lesions diagnosed by visual tactile and radiographic examinations, assessed the radiographic yield for clinical caries diagnosis, and estimated how accurately commonly used indicators for caries identified young adults who would benefit from radiographs at different thresholds. Overall, 576 patients aged 16–32 years seeking a first consultation were included. Patients were examined for caries and answered a validated questionnaire on sociodemographics and oral health behavior. Almost 10% of clinically sound approximal surfaces presented radiolucency in enamel/dentine. Of the clinically diagnosed noncavitated approximal and occlusal lesions, 22.5 and 17.7%, respectively, presented radiolucency reaching dentine at the radiographic examination. Noncavitated/enamel lesions detected radiographically were mainly at approximal surfaces (73.2%), while at occlusal surfaces these were negligible (0.7%). More than half of approximal dentine lesions were only detected radiographically (61.3%), while more than half of occlusal dentine lesions were only clinically diagnosed (57.1%). The hierarchical logistic regression analysis showed that patient’s caries activity, D1MFS scores ≥17, and frequent consumption of soft drinks were significantly associated with detection of approximal enamel/dentine lesions. Also, patient’s caries activity and frequent consumption of soft drinks were significantly associated with occlusal dentine caries (p ≤ 0.05). The indicator power of grouping these indicators as a predictor for the presence of radiographically detected lesions showed high sensitivity (0.84–0.91) and moderate specificity (0.64–0.73) for all surfaces and thresholds tested. In conclusion, radiographs increased significantly the number of approximal enamel/dentine and occlusal dentine lesions diagnosed. The ability to identify young adults with approximal lesions from the predictor was satisfactory. Bearing in mind that an essential contribution of bitewing radiographs to clinical examination is the detection of approximal noncavitated/enamel lesions that can be inactivated by nonoperative interventions, our results support the prescription of radiographs in young adults seeking a first consultation. Updating of current guidelines’ recommendation of radiographs is warranted.

Abstract:

RationaleExacerbations of chronic obstructive pulmonary disease (COPD) and pneumonia are two of the most common reasons for acute hospital admissions. Acute exacerbations and pneumonia present with similar symptoms in COPD patients, representing a diagnostic challenge with a significant impact on patient outcomes. The objectives of this study were to compare the prevalence of radiographic consolidation with the discharge diagnoses of hospitalised COPD patients.MethodsCOPD patients admitted to three UK hospitals over a 3-year period were identified. Participants were included if they were admitted with an acute respiratory illness, COPD was confirmed by spirometry and a chest radiograph was performed within 24 h of admission. Pneumonia was defined as consolidation on chest radiograph reviewed by two independent observersResultsThere were 941 admissions in 621 patients included in the final analysis. In 235 admissions, consolidation was present on chest radiography and there were 706 admissions without consolidation. Of the 235 admissions with consolidation, only 42.9% had a discharge diagnosis of pneumonia; 90.7% of patients without consolidation had a discharge diagnosis of COPD exacerbation. The presence of consolidation was associated with increased rate of high-dependency care admission, increased mortality and prolonged length of stay. Inhaled corticosteroid use was associated with recurrent pneumonia.ConclusionsPneumonia is underdiagnosed in patients with COPD. Radiographic consolidation is associated with worse outcomes and prolonged length of stay. Incorrect diagnosis could result in inappropriate use of inhaled corticosteroids. Future guidelines should specifically address the diagnosis and management of pneumonia in COPD.

Abstract:

Objectives This study aimed to describe a stress radiography to detect medial glenohumeral ligament rupture and to investigate the repeatability and reproducibility of this test. Materials and Methods Six adult Beagle cadavers were used. Both shoulders of each dog were randomly assigned into two groups: a normal shoulder group (NS group) and an affected shoulder group (AS group) where the medial glenohumeral ligament was arthroscopically transected. Goniometry, image analysis and radiography (normal and stress views) were performed before and after arthroscopic procedures. An abduction angle was determined for each stress view and an evaluation of the repeatability and the reproducibility was performed. Results Abduction angles were significantly larger in the AS group as measured by goniometer (p < 0.001), image analysis (p < 0.001) and radiographic stress view (p < 0.001) than in the NS group. The abduction angle difference varied from 12° to 29.3° (median difference of 19.4°) between NS and AS groups. There were good intra-observer and very good inter-observer agreements. A very good (r = 0.74; r = 0.72, respectively) significant (p < 0.001) positive correlation between goniometric and radiographic techniques and between image analysis and radiographic techniques was observed. Clinical Significance Shoulder abduction angles measured with a stress radiograph-specific view provide objective data that may contribute to diagnosis of medial shoulder instability in dogs.

Abstract:

Aim: The aim of this study was to investigate the prevalence of panoramic radiographic errors and to evaluate the correlation between age and panoramic radiographic error types.  Methodology: A total of 500 panoramic radiographs (259 male, 241 female) which have been taken for various reasons were randomly selected from the archive of our dentomaxillofacial radiology department. Patients were divided into six age groups and by sex. The assessed errors included the tongue not in contact with palate, slumped position, patients not biting on bite block, patient movement, the chin tipped high, the chin tipped low, the patient positioned forward, the patient positioned backward, patient’ head turned to one side, foreign bodies in the image, exposure errors, positioning error of the lips and missing image. Each radiograph was quality rated as excellent, diagnostically acceptable or unacceptable. Results: One or more errors were detected in 317 (63.4%) of the 500 panoramic radiographs, while no error was found in 183 (%36.6). It was observed that the most common error type was the slumped position (13.2%). Quality of the panoramic radiographs was evaluated according to the criteria, only 15% images were classified as “excellent”, 48.2% was as “inadequate for diagnosis” and 36.8% was as “adequate for diagnosis”. It was recorded that “slumped position” and “patient movement” errors were statistically significant in >56 years (p <0.05). Conclusion: Patients can be protected from unnecessary radiation reception by investigating the causes of panoramic radiographic errors and training of technicians in this direction.  How to cite this article: Aktuna Belgin C, Serindere G.
