MR Imaging is proving to an effective means for evaluating the shoulder. The use of a surface coil and high resolution scanning techniques have allowed detailed analysis of normal anatomy and suspected pathology of the shoulder. On the other way arthroscopic inspection provides a more extensive visualization of the joint in different positions. 31 patients, well documented, were studied with MR Imaging and correlated with findings in arthroscopy and open revision in some cases. The MR studies were retrospective interpreted without the knowledge of the results of other diagnostic procedures. For the evaluation of rotator cuff tears MRI proved to have a sensitivity of 83.3% and an accuracy of 90.3%. When Arthroscopy was correlated with open revision the sensitivity was 61.8% and the accuracy 78%. Labral pathology and Hill-Sachs lesions will be better evaluated in arthroscopy as in MRI (sensitivity of arthroscopy 100% and of MRI 69%, accuracy of arthroscopy 100% and of MRI 87.1%). With the high resolution scanning technique and a surface coil MRI has been shown to be useful in the evaluation of rotator cuff tears and impingement syndrome but not in diagnosis of labral pathology and Hill-Sachs lesions.
磁共振成像已被证明是评估肩部的一种有效手段。使用表面线圈和高分辨率扫描技术能够对肩部的正常解剖结构和疑似病变进行详细分析。另一方面，关节镜检查能在不同位置更全面地观察关节。对31例记录完备的患者进行了磁共振成像研究，并与关节镜检查结果以及部分病例的开放手术翻修结果进行了对比。磁共振成像研究是在不知其他诊断程序结果的情况下进行回顾性解读的。对于肩袖撕裂的评估，磁共振成像的敏感性为83.3%，准确性为90.3%。当关节镜检查与开放手术翻修结果对比时，敏感性为61.8%，准确性为78%。关节唇病变和希尔-萨克斯损伤在关节镜检查中比在磁共振成像中能得到更好的评估（关节镜检查的敏感性为100%，磁共振成像为69%；关节镜检查的准确性为100%，磁共振成像为87.1%）。借助高分辨率扫描技术和表面线圈，磁共振成像已被证明在评估肩袖撕裂和撞击综合征方面有用，但在诊断关节唇病变和希尔-萨克斯损伤方面则不然。
