本研究的目的是确定盆腔器官脱垂患者动态磁共振（MR）分期的观察者内和观察者间的可靠性。在30例盆腔器官脱垂患者中，由两名观察者独立评估动态MR图像。使用各种解剖学标志评估盆腔器官脱垂与耻骨尾骨线、H线和耻骨中线的关系。临床测量点的评估与耻骨中线。计算组内相关系数（ICC）以描述观察者内和观察者间的信度。总体而言，MR成像测量的观察者内和观察者间可靠性为极好至良好。耻骨尾骨线显示出上级的可靠性（ICC范围为0.70-0.99）。然而，临床测量点的可靠性仅为中等（ICC范围为0.20-0.96）。动态MR成像上定量脱垂分期的观察者内和观察者间可靠性为良好至极好。耻骨尾骨线似乎是最可靠的。
The aim of this study was to determine the intra- and interobserver reliability of dynamic magnetic resonance (MR) staging in pelvic organ prolapse patients. In 30 patients with pelvic organ prolapse, dynamic MR images were assessed independently by two observers. Various anatomical landmarks to asses pelvic organ prolapse were used in relation to the pubococcygeal line, H-line, and mid-pubic line. Clinical measurement points were assessed in relation to the mid-pubic line. The intraclass correlation coefficients (ICC) were calculated to describe the intra- and interobserver reliability. Overall, the intra- and interobserver reliability of MR imaging measurements was excellent to good. The pubococcygeal line showed superior reliability (ICC range 0.70-0.99). The reliability of clinical measurement points, however, were only moderate (ICC range 0.20-0.96). The intra- and interobserver reliability of quantitative prolapse staging on dynamic MR imaging were good to excellent. The pubococcygeal line appears the most reliable to use.
