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 ...

BACKGROUND Hysteroscopy is known as the most accurate test for diagnosing intrauterine pathology. To optimize fertility treatment, it is increasingly common to perform hysteroscopy as a routine procedure prior to IVF. However, literature on the reproducibility of screening hysteroscopy is lacking. Therefore, the aim of the study was to assess the intra- and inter-observer agreement in the indiv...

BACKGROUND Sagittal ratio values (SRVs) of cervical vertebrae are used for ante-mortem diagnosis of cervical vertebral stenotic myelopathy, but intraobserver and interobserver variability in measurement may influence radiographic interpretation of vertebral stenosis in horses with neurological disease. OBJECTIVES To determine intraobserver repeatability in SRVs, intra- and interobserver agree...

The purpose of this study was to assess inter- and intra-observer reproducibility of three different analytic methods to evaluate quantitative dynamic contrast-enhanced computed tomography (DCE-CT) measures from gastroesophageal junctional cancer. Twenty-five DCE-CT studies with gastroesophageal junction cancer were selected from a previous longitudinal study. Three radiologists independently r...

AIMS To examine the intra- and inter-observer reproducibility of pulmonary venous flow indices in patients with acute myocardial infarction. METHODS Two investigators, blinded to the results of the other examination, each examined 28 clinically stable post infarction patients in sinus rhythm. The two stored digital Doppler recordings from each patient were analysed in a blinded manner by both...

  Background: The I-Space is a radiological imaging system in which Computed Tomography (CT)-scans can be evaluated as a three dimensional hologram. The aim of this study is to analyze the value of virtual reality (I-Space) in diagnosing acute occult scaphoid fractures.   Methods: A convenient cohort of 24 patients with a CT-scan from prior studies, without a scaphoid fracture on radiograph, ye...

background: pre-clinical investigation of stem cells for repairing damaged myocardium predominantly used rodents, however large animals have cardiac circulation closely resembling the human heart. the aim of this study was to evaluate whether spect/ct myocardial perfusion imaging (mpi) could be used for assessing sheep myocardium following an acute myocardial infarction (mi) and response to int...
