Effect of Reader and Patient Parameters on the Performance o Last-Image-Hold for Fluoroscopic Grading of Vesicoureteric Reflux

摘要

OBJECTIVE. The purpose of this study is to determine the effect of different reader and patient parameters on the degree of agreement and the rate of misclassification of vesicoureteric reflux grading on last-image-hold frames in relation to spot-exposed frames from voiding cystourethrography (VCUG) as well as to determine the nature of reflux misclassification on last-image-hold frames.
