| 摘 要： | 目的 :探讨常规MRI和MR肩关节腔造影诊断肩袖撕裂的价值。方法 :采用 2 0个人离体肩关节标本 ,将常规MRI和追加MR肩关节腔造影检查结果与大体解剖、组织病理学结果进行比较。结果 :常规MRI检出肩袖部分撕裂的敏感度约为 61.9% ,追加MR肩关节腔造影后敏感度提高到 90 .5 %。常规MRI和MR关节腔造影检出肩袖完全撕裂的敏感度和特异度均为 10 0 %和 97.1%。结论 :在常规MRI检查的基础上追加MRI关节腔造影能提高检出肩袖部分撕裂的敏感度。

| Abstract: | Objective:To analyze the value of routine MRI examination and MR arthrography in diagnosis of rotator cuff tears.Methods: The study group consisted of 20 cadaver shoulders. All shoulders underwent both routine MRI and MR arthrography and were compared with the findings of gross anatomy and histopathology.Results: The sensitivity of routine MRI for detecting partial tears was 61.9% and further increased to 90.5% by adding MR arthrography. The sensitivity in detecting full-thickness tears was 100% and specificity was 97.1% for both routine MRI and MR arthrography.Conclusions:There is a higher sensitivity in detecting partial tears with routine MRI combined with MR arthrography. |
