肩袖损伤合并肩峰下撞击综合征的MRI表现

目的探讨肩袖损伤合并肩峰下撞击综合征的MRI影像表现。材料与方法对33例X线片无骨折但临床怀疑肩袖损伤或肩峰下撞击综合征的患者,用1.5 T MRI机检查,观察肩袖损伤及肩峰下撞击综合征在MR上的影像特征,分析两者的相关性,并与手术结果对比,计算准确率。结果 33例中肩袖损伤20例(合并肩峰下撞击综合征10例),肩峰下撞击综合征15例(合并肩袖损伤10例)。肩袖损伤和肩峰下撞击综合征术前MR诊断准确率分别约为95.0%、71.3%。结论肩关节MRI扫描对肩袖损伤及肩峰下撞击综合征的诊断有较高的临床应用价值,肩袖损伤者中至少半数合并肩峰下撞击综合征,临床和影像应予重视。

MRI features of rotator cuff injury with subacromial impingement syndrome

Objective:To explore the MRI features of rotator cuff injury with subacromial impingement syndrome (SIS).Materials and Methods:On X-ray examination of 33 cases without fracture but clinically suspected rotator cuff injury or SIS of the patients, using a 1.5 T MRI examination to observe the MRI imaging features of rotator cuff injury and subacromial impingement syndrome, analyzed the correlation between the two, and compared with the surgical ifndings, the accuracy of calculation.Results:In 33 cases of rotator cuff injury in 20 cases (10 cases with SIS), subacromial impingement syndrome 15 cases (10 cases with rotator cuff injury). The preoperative diagnosis rate of MRI was approximately 95%(rotator cuff injury), 71% (SIS).Conclusion:MRI scan of the shoulder joint of the rotator cuff injury and subacromial impingement syndrome diagnosis has a high clinical value, clinic and imaging should pay attention to.
