肩关节造影和MRI诊断肩袖损伤

目的评定肩关节造影、MRI诊断肩袖损伤的价值.材料和方法将33例临床诊断肩袖损伤患者的术前关节造影和MRI检查结果与术中观察结果的比较.另有13例复发性肩关节不稳、无肩袖损伤症状和体征的年轻患者术前的关节造影和MRI结果以及术中观察结果作为正常肩袖对照.结果在诊断肩袖完全断裂中,肩关节造影的敏感性为91%,特异性为100%;MRI的敏感性为95%,特异性为88%.结论关节造影诊断肩袖完全撕裂方法简单、迅速且费用低,易于广泛开展.但不能直接显示病变部位.MRI不但能够准确显示断裂的部位,反映肩袖病变的病理过程,而且能同时显示相邻组织的病理改变,更利于诊断和鉴别诊断.

Imaging of Rotator Cuff Tears: A Comparative Study of MRI with Arthrography and Surgery

Purpose: To evaluate arthrography and MRI in diagnosis of rotator cuff tear and its clinical significance. Materials and Meth ods: Thirty-three symptomatic patients with rotator cuff impingement were given both arthrography and MR imaging preoperatively to de tect the abnormalities of rotator cuff. 13 young patients whose complaints were about unstable shoulder without the symptoms of rotator cuff impingement were consider as normal rotator cuff contrast. Results: The results showed tat the sensitivity for diagnosis of rotator cuff com plete tear was 91% in arthrography and 95 % in MR imaging, the specificity was 100% in arthrography and 88% in MR image. Conclu sion:Both arthrography and MRI are able to display of rotator cuff complete tear with high sensitivity and specificity, Arthrography is cheaper than MRI, but it is unable to detect the incomplete tear. MRI not only display the place of the rotator cuff tear exactly, but also demonstrate the pathological changes of related structures.
