In order to test the criteria for abnormalities of the shoulder as seen on MR, 30 normal shoulders were examined. The examination included T1, proton and T2-weighted SE sequences and T2*-weighted FE sequences, using transverse, oblique coronary and oblique sagittal planes. In 57% there was increased signal intensity in the tendon of the rotator cuff; this might have been interpreted as a rupture of the cuff or tendinitis. Anatomical examination suggests that the finding is due to a normal layer between the long head of the biceps and the tendon joint complex. The anterior glenoid labrum could not be clearly delineated in 57% and the posterior labrum in 5%. In two cases there was a superior, postero-lateral defect in the head of the humerus. The currently accepted criteria for the MRT diagnosis of shoulder abnormalities need to be critically re-evaluated.
为了测试磁共振成像（MR）上所见肩部异常的标准，对30个正常肩部进行了检查。检查包括T1、质子和T2加权自旋回波（SE）序列以及T2*加权快速成像（FE）序列，采用横轴位、斜冠状位和斜矢状位平面。57%的肩部在肩袖肌腱处信号强度增加；这可能被解释为肩袖撕裂或肌腱炎。解剖学检查表明，该发现是由于肱二头肌长头与肌腱关节复合体之间的一层正常结构所致。57%的病例中前盂唇无法清晰显示，5%的病例中后盂唇无法清晰显示。两例肱骨头上存在上外侧缺损。目前公认的肩部异常磁共振成像诊断标准需要进行严格的重新评估。
