The Unified Classification System has expanded and updated the Vancouver Classification System and applied treatment principles to all periprosthetic fractures. This study assessed the reliability and validity of the Unified Classification System for femur fractures after hip arthroplasty. Thirty-eight radiographs were finally evaluated by 6 observers, 3 consultants and 3 trainees. Each observe...

PURPOSE To evaluate the interobserver reproducibility of two-dimensional shear wave elastography (2D-SWE) in measuring liver stiffness (LS) and to investigate factors related to liver 2D-SWE. MATERIALS AND METHODS A prospective study was conducted between August 2011 and August 2012 in rheumatoid arthritis patients who had been treated with methotrexate. Interobserver reproducibility of 2D-SW...

PURPOSE To develop and validate a robust standardized reporting tool for describing retinal findings in children examined for suspected abusive head trauma. DESIGN A prospective interobserver and intraobserver agreement study. METHOD An evidence-based assessment pro forma was developed, recording hemorrhages (location, layer, severity) and additional features. Eight consultant pediatric oph...

Background Quantitative first pass cardiac magnetic resonance (CMR) perfusion imaging has shown excellent interobserver agreement at a sector level in healthy volunteers and patients. In this study, we compare the myocardial blood flow (MBF) estimates in sector-wise and pixel-wise analysis. We also study the interobserver variability in pixel-wise MBF estimates from patients with coronary arter...

OBJECTIVE To determine the reliability of a rapid hematology stain for the cytological analysis of induced sputum samples. METHODS This was a cross-sectional study comparing the standard technique (May-Grünwald-Giemsa stain) with a rapid hematology stain (Diff-Quik). Of the 50 subjects included in the study, 21 had asthma, 19 had COPD, and 10 were healthy (controls). From the induced sputum s...

Purpose: To estimate interobserver agreement with regard to describing adnexalmasses using the InternationalOvarian Tumor Analysis (IOTA) terminology and the risk of malignancy calculated using IOTA logistic regression models LR1 and LR2, and to elucidate what explained the largest interobserver differences in calculated risk of malignancy. Experimental Design: One hundred and seventeen women w...
