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...

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 Quality control programs are necessary to maintain good clinical practice. Embryo grading has been described as one of the external quality assurance schemes. Although the evaluation of embryos is based on the assessment of morphological characteristics, considerable intra- and inter-observer variability has been described. In this multicentre study, the variability in the embryo eva...

PURPOSE To assess variability in the use of Tomita and modified Bauer scores in spine metastases. MATERIALS AND METHODS Clinical data and imaging from 90 patients with biopsy-proven spinal metastases, were provided to 83 specialists from 44 hospitals. Spinal levels involved and the Tomita and modified Bauer scores for each case were determined twice by each clinician, with a minimum of 6-week...

BACKGROUND/AIMS Narrow band imaging (NBI) endoscopy can be used for gross differentiation between the types of colonic polyps. This study was conducted as a retrospective study for estimation of the interobserver and intra-observer agreement of the pit pattern of the mucosal surface and the accuracy of histology prediction. METHODS A total of 159 patients underwent complete colonoscopy and 21...

BACKGROUND Histopathologic assessment of liver tissue is an essential step in management and follow-up of non-alcoholic fatty liver disease (NAFLD) while inter- and intra-observer variations limit the accuracy of these assessments. OBJECTIVES The aim of this study was to assess the inter- and intra-observer reproducibility of histopathologic assessment of liver biopsies based on NAFLD activit...

PURPOSE To evaluate the intra- and inter-observer variability of the North American Symptomatic Carotid Endarterectomy Trial (NASCET) and Warfarin-Aspirin Symptomatic Intracranial Disease (WASID) criteria for the evaluation of middle cerebral artery (MCA) stenosis using digital subtraction angiography (DSA). MATERIALS AND METHODS DSA images of 114 cases with 131 stenotic MCAs were retrospecti...

BACKGROUND The purpose of the study was to evaluate inter- and intra-observer variability in sonographic measurements of the cross-sectional area of the umbilical cord and the diameters of its vessels in low-risk pregnancies of 12 to 40 weeks of gestation. METHODS A prospective cross sectional study was performed in 221 pregnant women at different gestational ages. Measurements were carried o...
