摘　　要：目的　探讨外伤性冈上肌腱撕裂的MRI表现特点、诊断方法和关节腔MR造影的应用价值。方法　 18例均有明确的外伤史 ,开放性手术、关节镜检查或综合诊断最终明确 6例冈上肌腱完全撕裂、9例部分撕裂和 3例无撕裂。所有 18个病例均行常规SE序列MRI检查 ,另追加FE序列成像 11例、关节腔MR造影 9例、脂肪抑制序列成像 5例。结果　常规SE序列诊断冈上肌腱撕裂的准确率为 5 0 % (9/18) ,部分病例追加关节腔MR造影后准确率提高至 72 .2 % ;FE序列和脂肪抑制序列可提高检出病灶的敏感性。结论　冈上肌腱MRI诊断尚需采用SE序列、FE序列、脂肪抑制、关节腔造影等多种MR成像方法。Purpose To analyse the value of routine MRI examination and MR arthrography in diagnosis of traumatic tear of supraspinous tendon. Methods All 18 cases were carried out SE sequence, from that partial patients were appended MR arthrography, field echo and fat suppressed sequences imaging. Results Routine SE sequences had an accuracy of 50%. Appending with MR arthrography to partial cases, the diagnostic accuracy increased to 72.2%. FE and fat suppressed sequences were sensitive methods for detecting hyper intensity of tendon and edema of surrounding tissue. Conclusion MR arthrography, FE and fat suppressed sequences on the bases of SE sequence may be useful to the diagnosis of supraspinous tendon tears.
