PURPOSE Dynamic contrast-enhanced ultrasound (DCE-US) can be used for calculating organ perfusion. By combining bolus injection with burst replenishment, the actual mean transit time (MTT) can be estimated. Blood volume (BV) can be obtained by scaling the data to a vessel on the imaging plane. The study aim was to test interobserver agreement for repeated recordings using the same ultrasound sc...

PURPOSE To estimate interobserver agreement with regard to describing adnexal masses using the International Ovarian 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...

OBJECTIVE To evaluate if color-coded parametric images could help subjective visual analysis and improve interobserver agreement in the evaluation of segmental contraction (SC) in CMR. BACKGROUND Routine evaluation of SC in CMR remains mostly based on visual analysis of cine loops and subsequent interobserver variability remains a potential drawback. MATERIALS AND METHODS Three short axis c...

In 30 comatose head injured patients vestibulo-ocular responses were elicited by caloric stimulation. Inter- and intra-observer agreement of these responses was studied. The responses were shown in the form of a film to ten doctors who classified them into four categories: no reaction, tonic reaction, paradoxical nystagmus and nystagmus. The level of the coefficient Kappa (a chance-corrected me...

BACKGROUND AND PURPOSE Stroke remains primarily a clinical diagnosis, with information obtained from history and examination determining further management. We aimed to measure inter-rater reliability for the clinical assessment of stroke, with emphasis on items of history, timing of symptom onset, and diagnosis of stroke or mimic. We explored reasons for poor reliability. METHODS The study w...

BACKGROUND The objective of this investigation was to determine the inter- and intraobserver agreement when assessing embryo quality. METHODS This investigation included 4002 cleaved embryos from 7535 oocytes retrieved in 688 patients undergoing IVF cycles in a multicentre trial. Embryos were evaluated locally at the inverted microscope at 28, 44 and 68 h (+/-1 h) post-insemination. Digital i...

Interobserver agreement for the assessment of handicap in stroke patients was investigated in a group of 10 senior neurologists and 24 residents from two centers. One hundred patients were separately interviewed by two physicians in different combinations. The degree of handicap was recorded by each observer on the modified Rankin scale, which has six grades (0-5). The agreement rates were corr...
