摘要
目的 :探讨MRI(核磁共振成像 )和MR关节造影在肩部损伤中的诊断价值。方法 :自 1999年 3月至 1999年11月 ,共有 73个患者 75例肩关节接受了肩部MRI检查 ,其中 16例经关节镜或手术证实。对手术中所见与核磁共振表现进行比较。结果 :对肩袖完全撕裂 ,MRI和MR关节造影对全层撕裂诊断阳性率分别为 90 .6 %和 10 0 % ,特异性分别为 96 %和 97.6 %。MRI对肩袖部分撕裂诊断正确率低 ,可靠性差 ;MR关节造影诊断正确率达 80 % ,是肩袖部分撕裂诊断的可靠方法。MRI对急性Bankart损伤诊断阳性率 10 0 % ,对慢性或陈旧损伤 ,阳性率低 ,只有 33.3% ;而MR关节造影对慢性或陈旧损伤诊断阳性率达 10 0 %。对SLAP损伤 ,MR关节造影较MRI诊断阳性率高 ,但目前关节镜仍是SLAP损伤更可靠的定性诊断手段。
objective To investigate the value of MR imaging and MR arthrography in diagnosis of shoulder injuries. Methods 75 shoulders of 73 patients were evaluated with MR imaging during Mar. 1999 to Nov. 1999. 16 cases were confirmed by operations. The findings of MR were compared with those of operations. Results and conclusion The sensitivity of MRI and MR arthrography for complete cuff tear was 90.6% and 100% respectively, and speciality was 96% and 97.6% respectively. For partial cuff tear, MR imaging failed to get exactly right diagnosis, but MR arthrography is reliable for partial tear as the correct diagnostic rate is up to 80%. The sensitivity of MRI for acute Bankart lesion was 100%, but, for chronic or delayed injury , was lower, up to 33.3%, However, the sensitivity of MR arthrography for those chronic injuries was also up to 100%. For SLAP lesion, MR arthrography was more sensitive than MRI, but arthroscopy is still the only reliable diagnostic method.
