BACKGROUND The association between body composition (e.g. sarcopenia or visceral obesity) and treatment outcomes, such as survival, using single-slice computed tomography (CT)-based measurements has recently been studied in various patient groups. These studies have been conducted with different software programmes, each with their specific characteristics, of which the inter-observer, intra-ob...

BACKGROUND The Coronary Artery Disease Reporting and Data System (CAD-RADS) provides a lexicon and standardized reporting system for coronary CT angiography. OBJECTIVES To evaluate inter-observer agreement of the CAD-RADS among an panel of early career and expert readers. METHODS Four early career and four expert cardiac imaging readers prospectively and independently evaluated 50 coronary ...

introduction: vertical root fracture (vrf) is a complication which is chiefly diagnosed radiographically. recently, film-based radiography has been substituted with digital radiography. at the moment, there is a wide range of monitors available in the market for viewing digital images. the present study aims to compare the diagnostic accuracy, sensitivity and specificity of medical and conventi...

BACKGROUND This study was conducted to assess intra-observer and inter-observer agreements for the measurement of dual-input whole tumor computed tomography perfusion (DCTP) in patients with lung cancer. METHODS A total of 88 patients who had undergone DCTP, which had proved a diagnosis of primary lung cancer, were divided into two groups: (i) nodules (diameter ≤3 cm) and masses (diameter >3 ...

INTRODUCTION Abdominal auscultation is a part of the clinical examination of patients, but the determining factors in bowel sound evaluation are poorly described. The aim of this study was to assess inter- and intra-observer agreement in physicians' evaluation of pitch, intensity and quantity in abdominal auscultation. MATERIAL AND METHODS A total of 100 physicians were presented with 20 bowe...

BACKGROUND Quantification of cardiovascular magnetic resonance (CMR) myocardial perfusion reserve (MPR) at 1.5 Tesla has been shown to correlate to invasive evaluation of coronary artery disease (CAD) and to yield good inter-observer agreement. However, little is known about quantitative adenosine-perfusion CMR at 3 Tesla and no data about inter-observer agreement is available. Aim of our study...

AIM To determine the inter-observer variability for colon polyp morphology and to identify whether education can improve agreement among observers. METHODS For purposes of the tests, we recorded colonoscopy video clips that included scenes visualizing the polyps. A total of 15 endoscopists and 15 nurses participated in the study. Participants watched 60 video clips of the polyp morphology sce...

OBJECTIVE To assess inter- and intra-observer agreement in the detection of lymphadenopathy on chest radiography in children at risk for tuberculosis. PATIENTS AND METHODS Retrospective examination of the antero-posterior and lateral chest radiographs of children aged 1 month to 11 years discharged from the short-stay ward of the Red Cross Children's Hospital, Cape Town, with a diagnosis of t...

AIM To assess the reproducibility of pelvic floor biometric parameters by translabial three-dimensional ultrasound compared with the OmniView® reformatting technique. MATERIAL AND METHODS We performed a cross-sectional study involving 47 nulliparous women without symptoms of pelvic floor dysfunction. The hiatal area and right pubovisceral muscle width measurements were performed in the axial ...

BACKGROUND The purpose of our study was to evaluate inter-observer reliability of the Three-Column classifications with conventional Schatzker and AO/OTA of Tibial Plateau Fractures. METHODS 50 cases involving all kinds of the fracture patterns were collected from 278 consecutive patients with tibial plateau fractures who were internal fixed in department of Orthopedics and Trauma III in Shan...
