摘要: Background and Purpose Measurement of carotid plaque volume its progression are important tools for research patient management. In this study, we investigate the observer variability in measurement as determined by 3-dimensional (3D) ultrasound (US). We also effect interslice distances (ISD) repeated 3D US scans on variability. Materials Methods Forty images plaques (range, 37.43 to 604.1 mm3) were measured manual planimetry. applied ANOVA determine reliability. Plaque volumes with 9 ISDs ISD Additional from multiple scan acquisition Results Intraobserver interobserver reliabilities 94% 93.2%, respectively. decreased increasing 27.1%...
