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:
This study explores the day-to-day application of digital radiography (DR) within the X-ray environment. This study presents the voices of the radiographers' untold views, attitudes and experiences of DR through the process of observing, listening, retelling and interpreting junior and senior radiographers' responses. There were three stages to this ethnographic study. Firstly, exploring 'what radiographers did' environment by observing clinical practices. This provided 'first-hand' experience of action-in-process. Secondly, 22 semi-structured interviews were undertaken, directed by emerging themes and informal discussions from the clinical observations. Semi-structured interviews provided an understanding of the experiences, behaviours and attitudes of radiographers providing a deeper understanding of the relationship between practice and context. Thirdly, X-ray experiments were undertaken contributing to 'what had been seen and said by participants'. This data was later triangulated to support the research objectives outlined in this PhD research. Observation and interview data were analysed using thematic analysis and grouped into four overarching categories; learning, radiographer challenges, ionising radiation and patient care delivery. X-ray experimental data was inputted into SPSS and later coded. The qualitative data had numerous codes, which generated themes and could be linked in order to generate theoretical descriptions. Multiple-linear regression analysis and Pearson's Correlation provide statistically significant values (p < 0.001) for the experimental models contributing to 'what had been seen and said' by radiographers in the clinical environment. This thesis provides new insights into general radiographic practices using advancing technology. The conclusions that can be drawn from the empirical data is that advancing technology has impacted the day-to-day practices of diagnostic radiographers. Complex phenomena include; current knowledge and understanding, the practice of keeping doses 'as low as reasonably practicable' and impact on patient care delivery. These insights suggest that healthcare and academic environments may require additional support in the aim of delivering optimum patient care.

Abstract:
Radiographic modalities are used in addition to clinical methods to gain information about the patients. In the examination of the periodontium, which is comprised of the gingiva, alveolar bone, periodontal ligament, and cementum, the radiographic examination plays an integral role for diagnosis of periodontal disease. The diagnosis periodontitis is based on a finding of alveolar bone loss. Changes of the alveolar bone can be assessed by different radiographic modalities, such as intraoral radiography (bitewing and periapical radiography) and panoramic radiography. Analysis of alveolar bone loss (alveolar bone level, detection of vertical bone defect and furcation involvement) in radiographic modalities and a systematic review could be helpful to suggest the more applicable radiographic methods for diagnosis of periodontal disease. The purpose of the present study was to examine diagnostic properties of panoramic radiography for the assessment of alveolar bone loss for the diagnosis of periodontal diseases as compare to posterior bitewing radiography. For 96 patients panoramic and posterior bitewing radiographs were performed and results of analysis of visibility of radiographic images and assessment of alveolar bone loss were compared. Also, the systematic review on diagnostic properties of panoramic radiography in the assessment of alveolar bone loss was performed. Based on the results of this study, recommendations for clinical practice and for research were proposed.<br>Rentgeniniai tyrimo metodai taikomi, kad būtų papildyti klinikinio tyrimo duomenys. Tiriant periodontą, kurį sudaro dantenos, dantinė atauga, periodonto raiščiai ir cementas, rentgeninis tyrimas svarbus diagnozuojant periodonto ligas, nes jo metu nustatomi dantinės ataugos pokyčiai.

Abstract:
Symptomatic apical periodontitis (SAP) is indicative of inflammation of the periodontal ligament. It may or may not be accompanied by radiographic changes and may occur with vital or necrotic pulpal diagnosis. Purpose of this study was to analyze clinical and radiographic presentations of SAP in a retrospective electronic dental chart and digital radiograph review utilizing the endodontic diagnostic template note of predoctoral dental school patients presenting with SAP. The aim was to determine prevalence of periapical radiolucencies (PARLs) in SAP, association of SAP to pulpal diagnosis, and define associated radiographic changes. Most prevalent pulpal diagnosis with SAP was symptomatic irreversible pulpitis (44%). A tooth presenting with SAP was more likely to have an intact lamina dura, but presented with a PARL 38% of the time. When a PARL was present the most common pulpal diagnosis was pulp necrosis however, 24.5% of teeth presented with a vital pulp diagnosis and lesions <2mm.

Abstract:
Dissertação de Mestrado Integrado em Medicina Veterinária<br>O exame radiográfico cardíaco, compreende uma avaliação qualitativa e quantitativa da silhueta cardíaca, vasos principais, pulmonares, e possíveis acumulações de fluído secundárias a congestão. O objetivo deste estudo retrospetivo é determinar a capacidade diagnóstica de diferentes Índices radiográficos na deteção de doença cardíaca (DC) felina. Como tal, selecionou-se uma amostra de 31 gatos, 10 normais (50% de cada género) e 21 com DC (62% machos, 38% fêmeas). No grupo de DC, criaram-se três subgrupos: DC com e sem dilatação do átrio esquerdo (DAE), e DC com envolvimento do coração direito, cada um destes detendo 10, 11 e 9 felinos, respetivamente. O subgrupo de DC com DAE foi novamente dividido em três graus de dilatação mediante o rácio AE/Ao, baseado na ecocardiografia: Ligeira (L) superior a 1,5, Moderada (M) entre 1,5 e 2, e Grave (S) maior que 2. Utilizou-se a projeção Laterolateral, efetuando-se as medições necessárias aos seguintes Índices Radiográficos: L; C; VHS; C x L; C x L/ S4; C x L/ T4; (C + L)/S4, onde L representa a largura da silhueta cardíaca, e C o comprimento; S4 e T4 o comprimento da quarta estérnebra e vértebra torácica, respetivamente. Realizaram-se testes de correlação entre DAE e os Índices, e, como objetivo basal, determinou-se o poder diagnóstico de cada um destes Índices na deteção de DC e dos vários subgrupos de DC, comparativamente ao grupo de gatos normais. Todos os Índices apresentaram correlação significativa (P<0,05) com o rácio AE/Ao, detendo maior associação o C x L/S4 (ρ- 0,57) e (C + L)/S4 (ρ- 0,55). A radiografia revelou maior capacidade diagnóstica na deteção de DC com DAE e DC com envolvimento do coração direito. Na sinalização de DC com DAE o Índice com maior poder diagnóstico foi o VHS (AUC de 0,990) com valores cutoff de 8,5v e 8,9v, com sensibilidades e especificidades de 100%-90%, e 90%-100%, respetivamente. Logo de seguida, com AUC de 0,910, surgem o C x L/S4 e o C x L/T4, cujos cutoff foram de 16,2 cm e 21,1 cm (sensibilidade de 90%, e especificidade de 100% e 90%, respetivamente). Na identificação de DC com envolvimento direito os Índices com melhor aptidão foram C x L/T4 e C + L/S4 (AUC de 0,844) com cutoffs de 20,2 cm e 6,7; e 78%-100%, 78%-80% de sensibilidade-especificidade, respetivamente. Os novos Índices possuem melhor poder diagnóstico face ao VHS na deteção de DC com envolvimento direito, e DC sem DAE. Estes poderão ser aplicados como complemento ao VHS, frequentemente empregue na prática clínica, na tentativa de melhorar a informação diagnóstica obtida, particularmente nos casos sem DAE associada (embora com baixa capacidade), ou na DC com envolvimento direito, onde, superados os cutoffs obtidos, poderá alertar para uma análise mais detalhada do lado direito na ecocardiografia, ou de causas para esta alteração na radiografia. Contudo, apesar da radiografia constituir uma boa ferramenta inicial de screening/rastreio, exclusão de diferenciais e acompanhamento, a ecocardiografia continua a ser o gold standard na confirmação e caracterização do tipo de DC felina.<br>ABSTRACT - The cardiac radigraphic exam includes a qualitative and quantitative evaluation of the cardiac silhouette, great vessels, pulmonary vessels, and possible accumulation of fluid secondary to congestion. The objective of this retrospective study is to assess the diagnostic capacity of different radiographic Indexes in the detection of feline heart disease (HD). As such, a sample of 31 cats, 10 normal (50% of each gender) and 21 with HD (62% male, 38% female) was selected. In the group of HD three subgroups were created: HD with and without left atrial dilation (LAD), HD with involvement of right heart, each one of these containing 10, 11 and 9 felines, respectively. The subgroup of HD with LAD was again divided in three degrees of dilation according to the ratio LA/Ao, based on echocardiography: Mild (L) greater than 1,5, Moderate (M) between 1,5 and 2, and Severe (S) bigger than 2. The Laterolateral projection was used, having taken place the measures necessary to the following radiograpic Indexes: L; C; VHS; C x L; C x L/ S4; C x L/ T4; (C + L)/S4, where L represents the width of the cardiac silhouette, and C the lenght; S4 and T4 the lenght of the fourth sternnebra and toracic vertebra, respectively. Correllation tests were performed between LAD and the Indexes, and, being the baseline objective, the diagnostic acuity of each of these Indexes was determined in the detection of HD and of the various subgroups of HD, comparing to the group of normal cats. All the Indexes presented significant correlation (P<0,05) with the ratio LA/Ao, having greater association the C x L/S4 (ρ- 0,57) and (C + L)/S4 (ρ- 0,55). The radiography revealed better diagnostic capacity in the detection of HD with LAD and HD with right heart envolvement. In signaling HD with LAD, the VHS was the Index with bigger diagnostic power (AUC of 0,990), with cutoff values of 8,5v and 8,9v, with sensitivities and specificities of 100%-90%, and 90%-100%, repectively. Right after, with AUC of 0,910, apear the C x L/S4 and the C x L/T4, whose cutoff where 16,2 cm and 21,1 cm (sensitivity of 90%, and specificity of 100% and 90%, respectively). In the identification of HD with right heart involvement the Indexes that showed best acuity were C x L/T4 and C + L/S4 (AUC of 0,844) with cutoffs of 20,2 cm and 6,7; and 78%-100%, 78%-80% of sensitivity-specitivity, respectively. The new Indexes possess better diagnostic power compared to the VHS in detecting HD with right heart involvement, and HD without LAD. These could be applied as a complement to VHS, frequently employed in clinical practice, as an atempt to improve the diagnostic information obtained, particularly in cases without LAD associated (though with low capacity), or in HD with right heart involvement, where, once surpassed the obtained cutoffs, could be useful to alert for a more detailed analysis of the right side in echocardiography or to causes for this alteration in the radiography. However, despite radiography being a good initial tool for screening, exclusion of differentials and monitoring, the ecocardiography still stands as the gold standard for confirmation and characterization of the feline HD type.<br>N/A

Resumo: A redução da dose de radiação ao paciente é aceita em Radiologia Odontológica, com a finalidade de diminuir os riscos associados ao exame radiográfico. Para atingir este objetivo, além do avanço tecnológico ocorrido nas últimas décadas, devemos considerar a importância do Critério de Seleção para o paciente e da prescrição radiográfica na indicação correta do tipo de radiografia necessária para cada um deles. O objetivo deste trabalho foi avaliar a prescrição radiográfica de pacientes atendidos pelo Serviço de Medicina Bucal da Faculdade de Odontologia de Araraquara - UNESP durante o período de 1989 a 1993. Selecionamos 396 prontuários que constituiu a totalidade dos que continham exames radiográficos. Para a análise da prescrição radiográfica, consideramos as informações obtidas da ficha clínica e da interpretação das radiografias, utilizando os Critérios de Seleção e a análise de decisão clínica. Os resultados demonstraram um alto índice de pacientes com prescrição incorreta (44,0%); tendo em 24,7% dos pacientes ocorrido mais de uma radiografia prescrita incorretamente. Com relação ao tipo de técnica com prescrição incorreta, em 31,6% dos pacientes foi realizada a radiografia panorâmica, vindo a seguir a oclusal (28,7%), outro (17,2%) e a associação da panorâmica e oclusal (12,6%).

A correct radiographic prescription means the correct radiographic view for each individual patient is used. The purpose of this study was to analyse the radiographic prescription of patients in the Oral Medicine Clinic, at Araraquara Dental School - UNESP, during the period between 1989 and 1993. The sample of this study was all of the files that had any type of radiographic examination (396). For the radiographic prescription we have considered the informations from the files and the radiographic interpretation based on Selection Criteria and clinical decision analysis methods.The results showed a high percentage of patients with incorrect prescription ( 44.0%); 24.7% had at least more than one incorrect prescription.From the radiographic views, the panoramic radiographic was prescribed incorrectly in 31.6% of the patients, following by an occlusal view (28.7%) , others (17.2%) and the association of panoramic and occlusal views (12.6%). The patients with soft tissues diseases have had the highest percentage of incorrect prescription (35.0%), following by salivary gland diseases, including the tumors (13.5%); others (10.1%); TMJ disorders (9.0%); jaw's inflamation and infections (6.8%); benign tumors (5.6%) and malignant tumors (5.6%). The radiographic examination contributed for diagnosis and treatment in 62.9% of the patients.The high percentage of incorrect radiographic prescription shows the importance to develop the guidelines in Oral Medicine.

Dissertação de Mestrado Integrado em Medicina Veterinária<br>Em equinos as doenças músculo-esqueléticas são a maior causa de diminuição de performance, interrupção do treino e invalidez prematura para competições. A deteção precoce das patologias, na maioria das vezes, significa um melhor prognóstico e uma redução nos custos globais do tratamento. A termografia pode ser uma mais-valia na deteção precoce de certas doenças e consequentemente na possibilidade de diminuir o impacto de uma lesão no desempenho desportivo do animal. As utilizações para as quais a sua utilidade é reconhecida são cada vez mais numerosas e variadas. O estudo efetuado pode contribuir para utilização da termografia em clínica de equinos, na medida em que pretende verificar de que forma podemos relacionar a termografia com outros métodos de diagnóstico frequentemente utilizados pelo médico veterinário, na sua prática diária. A amostragem foi efetuada tendo em conta o diagnóstico da patologia e o tratamento efetuado. Foram incluídos neste estudo cavalos examinados devido a lesões músculo-esqueléticas que originaram claudicação, diagnosticados com osteoartrite, exostoses dos metacarpianos, síndrome navicular ou osteocondrose/osteocondrite dissecante. Embora com algumas limitações, este trabalho parece apontar no sentido de podermos relacionar as alterações de temperatura detetadas por termografia com o diagnóstico de claudicação e o diagnóstico radiográfico.<br>ABSTRACT - Musculoskeletal diseases are a major cause of reduced performance, training interruption and premature competitions retirement for horses.

Thermography can be an asset in the early detection of some diseases and therefore the possibility of reducing the impact of an injury on the animal’s sports performance of the animal. The uses to which its usefulness is recognized are increasingly numerous and varied. The study conducted can contribute to the use of thermography in equine practice, in the way that it aims to ascertain how to relate thermography with other diagnostic methods often used by the veterinarian, in their daily practice. Sampling was performed taking into account the diagnosis of disease and treatment effected. The study included horses examined due to musculoskeletal injuries that originated claudication, diagnosed with osteoarthritis, exostosis of the metacarpal bones, navicular syndrome or osteochondrosis / osteochondritis dissecans. Although with some limitations, this study seems to point in the direction that we can relate the temperature changes detected by thermal imaging with lameness and radiographic diagnosis.

Dissertação de Mestrado Integrado em Medicina Veterinária<br>A doença articular degenerativa (DAD) apresenta uma etiologia multifatorial, envolvendo fatores genéticos, biomecânicos e bioquímicos, caracterizando-se pela existência de degeneração da cartilagem articular com produção de novo tecido ósseo. A sua prevalência na população felina parece aumentar com a idade, sendo o seu diagnóstico feito com base na associação de sinais clínicos e alterações ao exame radiográfico. O presente estudo teve por base uma amostra de 100 pacientes felinos (N=100) com exame radiográfico e anamnese disponíveis. Os objetivos principais foram calcular a prevalência de DAD na presente amostra e avaliar a frequência e a gravidade das lesões no esqueleto axial e apendicular. Para isto, os exames radiográficos dos 100 animais foram avaliados por dois observadores quanto à existência de sinais radiográficos compatíveis com DAD e respetivo grau de gravidade. Na população avaliada, a prevalência de sinais radiográficos compatíveis com DAD foi de 38%. Os esqueletos apendicular e axial apresentaram alterações em 24% e 25% dos animais, respetivamente. Existiam lesões simultaneamente na coluna e nas articulações apendiculares em 11% dos animais avaliados. A articulação do esqueleto apendicular mais frequentemente afetada foi a articulação úmero-rádio-ulnar, e a que apresentou lesões de maior gravidade foi a articulação femoro-tíbio-patelar. No esqueleto axial, o segmento da coluna com maior frequência de alterações compatíveis com DAD foi a região torácica. Já a região lombar apresentou scores de gravidade mais elevados quando comparado com os restantes segmentos. Não foi encontrada uma associação estatisticamente significativa entre a presença de sinais radiográficos e o sexo ou a idade. No entanto, foi encontrada uma relação estatisticamente significativa entre a raça do animal e a presença de DAD (p<0,05). A prevalência encontrada (38%) é largamente superior ao número de animais da amostra em que se suspeitava da existência de doença articular (3%). Além de frequente, a DAD é sub-diagnosticada na prática clínica, sendo responsável por provocar dor crónica nos pacientes felinos passando muitas vezes desapercebida quando a avaliação se baseia na anamnese e nos sinais clínicos. Sendo assim, o exame radiográfico e sua correta apreciação reveste-se de extrema importância de modo a identificar e possibilitar o tratamento desta doença.<br>ABSTRACT - Prevalence of radiographic changes associated with degenerative joint disease in the domestic cat – retrospective study of 100 cases - Degenerative joint disease (DJD) has a multifactorial etiology that involves genetics, biomechanics and biochemistry factors and it is characterized by the degeneration of the cartilage with production of new bone tissue. Its prevalence in the feline population increases with age and its diagnosis takes in consideration the clinical signs as well the radiographic chances. The present study used a sample of 100 feline patients (N=100) with radiographic exams and anamnesis available. The main objective was to calculate DJD prevalence in the sample as well as determine the frequency and severity of these lesions in the axial and appendicular skeleton. To accomplish this, radiographic exams from 100 patients were observed and evaluated by two different observers, who assessed them for the presence of radiographic signs compatible with DJD and respective degree of severity. In the evaluated population, the prevalence of radiographic signs compatible with DJD was 38%. The appendicular and axial skeleton had shown changes in 24% and 25% of the animals, respectively. There were lesions in both spine and appendicular joints in 11% of the population. The most frequently affected joint of the appendicular skeleton was the elbow, and the one that presented with the most severe lesions was the knee. In what concerns to the axial skeleton, the segment of the spine with the highest frequency of compatible with DJD was the thoracic region. The lumbar region presented higher severity scores when compared to the other segments. No statistically significant association was found between the presence of radiographic signs and sex or age. However, a statistically significant relationship was found between the patient’s breed and the presence of DJD (p<0,05. The prevalence of DJD determined (38%) is significantly higher than the number of patients in which it was suspected (3%). DJD is not only frequent and responsible for causing chronic pain in feline patients, but also under-diagnosed in the clinical practice, going unnoticed when the evaluation is based on anamnesis and clinical signs. Therefore, the radiographic examination and its correct evaluation is of extreme importance to identify and make the treatment of this disease possible.<br>info:eu-repo/semantics/publishedVersion

Abstract:
[This Proceedings paper was revised and published in the 2019 issue of the journal Issues in Informing Science and Information Technology, Volume 16] Aim/Purpose: The aim of this study was to develop a prototype of an information-generating computer tool designed to automatically map the dental restorations in a panoramic radiograph. Background: A panoramic radiograph is an external dental radiograph of the oro-maxillofacial region, obtained with minimal discomfort and significantly lower radiation dose compared to full mouth intra-oral radiographs or cone-beam computed tomography (CBCT) imaging. Currently, however, a radiologic informative report is not regularly designed for a panoramic radiograph, and the referring doctor needs to interpret the panoramic radiograph manually, according to his own judgment. Methodology: An algorithm, based on techniques of computer vision and machine learning, was developed to automatically detect and classify dental restorations in a panoramic radiograph, such as fillings, crowns, root canal treatments and implants. An experienced dentist evaluated 63 panoramic anonymized images and marked on them, manually, 316 various restorations. The images were automatically cropped to obtain a region of interest (ROI) containing only the upper and lower alveolar ridges. The algorithm automatically segmented the restorations using a local adaptive threshold. In order to improve detection of the dental restorations, morphological operations such as opening, closing and hole-filling were employed. Since each restoration is characterized by a unique shape and unique gray level distribution, 20 numerical features describing the contour and the texture were extracted in order to classify the restorations. Twenty-two different machine learning models were evaluated, using a cross-validation approach, to automatically classify the dental restorations into 9 categories. Contribution: The computer tool will provide automatic detection and classification of dental restorations, as an initial step toward automatic detection of oral pathologies in a panoramic radiograph. The use of this algorithm will aid in generating a radiologic report which includes all the information required to improve patient management and treatment outcome. Findings: The automatic cropping of the ROI in the panoramic radiographs, in order to include only the alveolar ridges, was successful in 97% of the cases. The developed algorithm for detection and classification of the dental restorations correctly detected 95% of the restorations. ‘Weighted k-NN’ was the machine-learning model that yielded the best classification rate of the dental restorations - 92%. Impact on Society: Information that will be extracted automatically from the panoramic image will provide a reliable, reproducible radiographic report, currently unavailable, which will assist the clinician as well as improve patients’ reliance on the diagnosis. Future Research: The algorithm for automatic detection and classification of dental restorations in panoramic imaging must be trained on a larger dataset to improve the results. This algorithm will then be used as a preliminary stage for automatically detecting incidental oral pathologies exhibited in the panoramic images.

Abstract:
The majority of musculoskeletal (MSD) impairments in the cervical (neck) region cannot be determined through MRIs or radiographs but are instead diagnosed through a clinical assessment technique using palpation. Palpatory diagnostic techniques are based on range of motion (ROM), tissue textures, quality of motion (smooth, elastic or bone on bone) and symmetry [1]. However, because scientifically accepted objective measures are not yet available to complement a clinical diagnosis, the documentation of the impairment as well as effects of treatment can be challenging. Thus, the purpose of this research was to explore the use of three-dimensional kinematics as a potential tool for relating movement patterns of the head/neck to clinical diagnosis and documenting treatment effects.

Abstract:
Orthopaedic extremity injuries present a large medical and financial burden to the United States and world-wide communities [1]. Approximately six million long bone fractures are reported annually in the United States and approximately 10% of these fractures do not heal properly. Though the exact mechanism of impaired healing is poorly understood, many of these non-unions result when there is a communited condition that does not proceed through a stabilized healing pathway [2]. Currently, clinicians may monitor healing visually by radiographs, or via manual manipulation of the bone at the fracture [3]. Unfortunately, the course of aberrant fracture healing is not easily diagnosed in the early period when standard radiographic information of the fracture is not capable of discriminating the healing pathway. Manual assessment of fracture healing is also an inadequate diagnostic tool in the early stages of healing [4].
