background: magnetic resonance imaging (mri) has long been considered a perfect imaging study for evaluation of shoulder pathologies despite occasional discrepancies between mr reports and arthroscopic findings. in this study we aim to evaluate impact of imaging center as an indicator of image quality on accuracy of mri reports in diagnosis of rotator cuff tendon pathologies. methods: we review...

BACKGROUND To examine nurse-physician inter-observer agreement on triage categorization and analyze their differences for future reference. METHODS A retrospective observational study was performed. Patients entering a 3500-bed medical center emergency department (ED) from July 1 to 31, 1998 were randomly selected. We compared triage assignments made by nurses and 2 ED physicians, and examine...

A critical step in radiotherapy treatment planning process is to accurately locate the tumor and determine its extent. Variability in gross tumor volume (GTV) delineation is a major source of systematic error in conformal radiotherapy. CT scan is the principle source of imaging data used for defining GTV for planning conformal therapy. CT is widely available less costly and compatible with radi...

PURPOSE Functional results of index pollicisation are usually assessed by the clinical score of Percival. This score is based on elementary hand movements and does not reflect the function of the neo thumb in daily life activities. The aim of this study was to develop a new video-assisted scoring system based on daily life activities to assess index pollicisation functional outcomes. METHODS ...

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 and Aim: Cone beam computed tomography (CBCT) produces high-quality data in periodontal diagnosis and treatment planning. The aim of this study was to compare the accuracy of CBCT with intraoral digital and conventional radiography in the measurement of periodontal bone defects.  Methods and Materials: In this diagnostic research, two hundred and eighteen artificial osseous d...

The diagnosis of digital dermatitis (DD) in cows is crucial for researchers to evaluate the effectiveness of control measures. The objective of this study was to evaluate intra- and inter-observer agreement and accuracy of a simple method to score DD lesions that is based on the inspection of cleaned feet in the milking parlor with a swiveling mirror and a powerful headlamp. The hind feet of 24...

BACKGROUND Recent studies show that virtual histology intravascular ultrasound (VH-IVUS) can identify plaques at high risk of rupture, such as thin-capped fibroatheromata, raising the possibility of immediate targeted intervention. However, plaque classification entails border recognition and subjective assessment of plaque architecture, introducing inter-observer variability without confirmati...

Abstract Camera traps are a popular tool in terrestrial wildlife research due to their low costs, easy operability, and usefulness for studying wide array of species questions. The vast numbers images they generate often require multiple human data extractors, yet accuracy inter-observer variance rarely considered. We compared results from 10 observers who processed the same set multi-species c...
