To determine the diagnostic performance of magnetic resonance (MR) imaging in the evaluation of suspected rotator cuff tears, eight asymptomatic volunteers and 32 patients with rotator cuff tendonopathy who underwent surgery were examined with MR imaging. Twenty-four of these patients also underwent contrast arthrography. The ability of MR imaging to depict the size of cuff tears and the quality of torn tendon edges was also evaluated. The MR imaging and arthrographic studies were reviewed without knowledge of surgical results or of the other studies. A scoring system was developed and a score assigned to each patient's MR study. The sensitivity of MR imaging for all tears (partial and full thickness) was 0.91, and the specificity was 0.88; whereas the sensitivity and specificity of arthrography were each 0.71. The scoring system improved the sensitivity to 1.0 and the specificity to 0.92. Linear regression analysis showed excellent correlation between preoperative assessment of the size of rotator cuff tears and measurement at surgery (r = .95).
为确定磁共振（MR）成像在评估疑似肩袖撕裂中的诊断性能，对8名无症状志愿者和32例接受手术的肩袖肌腱病患者进行了MR成像检查。其中24例患者还接受了关节造影。还评估了MR成像描绘肩袖撕裂大小和撕裂肌腱边缘质量的能力。在不知道手术结果或其他研究的情况下对MR成像和关节造影研究进行了回顾。制定了一个评分系统，并为每位患者的MR研究分配了一个分数。MR成像对所有撕裂（部分厚度和全层厚度）的敏感性为0.91，特异性为0.88；而关节造影的敏感性和特异性均为0.71。评分系统将敏感性提高到1.0，特异性提高到0.92。线性回归分析显示术前对肩袖撕裂大小的评估与手术测量之间具有极好的相关性（r = 0.9
