BACKGROUND This study aimed to assess inter-observer variability between the original diagnostic reports and later review by a specialist in breast pathology considering lobular neoplasias (LN), columnar cell lesions (CCL), atypical ductal hyperplasia (ADH), and ductal carcinoma in situ (DCIS) of the breast. METHODS A retrospective, observational, cross-sectional study was conducted. A total ...

OBJECTIVE This study objective was to evaluate interobserver agreement between individual pairs of three nuclear medicine physicians in interpretation of renal cortical scintigraphy in children with respect to the mode of acquisition (planar vs. SPECT), diagnoses and kidney site (left vs. right). MATERIALS AND METHODS Thirty children were imaged in planar and SPECT mode per protocol upon the ...

BACKGROUND Teledermatology may be less optimal for skin neoplasms than for rashes. OBJECTIVES We sought to determine agreement for skin neoplasms. METHODS This was a repeated measures study. Each lesion was examined by a clinic dermatologist and a teledermatologist; both generated a primary diagnosis, up to 2 differential diagnoses, and management. Macro images and polarized light dermoscop...

Measuring agreement between qualified experts is commonly used to determine the effectiveness of a diagnostic procedure. Many methods are available for assessing agreement, including Cohen’s kappa, which is a very popular summary measure of agreement due to its appealingly simple usage and interpretation. However, it has been previously shown that a number of flaws exist in its usage, which can...

PURPOSE To assess agreement between monoscopic and stereoscopic photography for research classification of the severity of diabetic retinopathy (DR). METHODS Monoscopic digital (MD) images were compared with stereo digital (SD) and film (SF) photographs from a 152-eye cohort with full-spectrum Early Treatment Diabetic Retinopathy Study (ETDRS) severity levels for agreement on severity level, ...

BACKGROUND AND PURPOSE Several angiographic features of brain arteriovenous malformations (BAVMs) have been associated with an increased risk of hemorrhage. However, interpretation of these features may not be consistent between observers. We conducted a study to determine inter- and intraobserver agreement of various angioarchitectural characteristics of BAVM. MATERIALS AND METHODS Two exper...

The kappa statistic is frequently used to test interrater reliability. The importance of rater reliability lies in the fact that it represents the extent to which the data collected in the study are correct representations of the variables measured. Measurement of the extent to which data collectors (raters) assign the same score to the same variable is called interrater reliability. While ther...

PURPOSE To characterize the inter- and intraobserver variability of qualitative, non-disk contour degenerative findings of the lumbar spine at magnetic resonance (MR) imaging. MATERIALS AND METHODS The case accrual method used to perform this institutional review board-approved, HIPAA-compliant retrospective study was the random selection of 111 interpretable MR examination cases of subjects ...

BACKGROUND & AIMS The study and management of reflux esophagitis require an endoscopic classification system founded on esophageal lesions that can be reproducibly identified. The aim of this study was to investigate interobserver agreement for the identification of endoscopic lesions typical of reflux esophagitis. METHODS Paired comparisons of observers' descriptions were obtained. Seventeen...
