磁共振成像（MRI）越来越多地应用于子宫肌瘤的评估。然而，关于MRI在子宫肌瘤评估中的可重复性知之甚少。本研究评价了在子宫动脉栓塞术（UAE）中评估子宫肌瘤和伴发子宫腺肌症的观察者间和观察者内差异。40例有症状的子宫肌瘤患者（平均年龄：44.5岁）接受了T1和T2加权MRI检查，这些患者计划接受UAE。为了研究观察者间和观察者内的一致性，40张MR图像由两名观察者独立评估，并在4个月后由两名观察者重新评估。分别使用Cohen kappa统计量和分类变量和连续变量的组内相关系数计算观察者间和观察者内一致性。子宫体积（kappa = 0.99，p < 0.0001）、主要肌瘤体积（kappa = 0.98，p < 0.0001）
Magnetic resonance imaging (MRI) is increasingly applied in the evaluation of uterine fibroids. However, little is known about the reproducibility of MRI in the assessment of uterine fibroids. This study evaluates the inter- and intraobserver variation in the assessment of the uterine fibroids and concomitant adenomyosis in women scheduled for uterine artery embolization (UAE). Forty patients (mean age: 44.5 years) with symptomatic uterine fibroids who were scheduled for UAE underwent T-1- and T-2-weighted MRI. To study inter- and intraobserver agreement 40 MR images were evaluated independently by two observers and reevaluated by both observers 4 months later. Inter- and intraobserver agreement was calculated using Cohen's kappa statistic and intraclass correlation coefficient for categorical and continuous variables, respectively. Inter-observer agreement for uterine volumes (kappa = 0.99, p < 0.0001), dominant fibroid volumes (kappa = 0.98, p
