摘　　要：目的:评价肩关节MR造影三维各向同性脂肪抑制快速自旋回波(SPACE)序列对上盂唇前后撕裂(SLAP损伤)的诊断价值。方法:影像诊断医师回顾性分析经关节镜证实的肩关节MR造影图像,判定有无SLAP损伤及分型,对比常规二维序列和SPACE序列对SLAP损伤的敏感度、特异度及准确率,比较常规二维序列与SPACE序列的诊断价值。结果:肩关节镜证实SLAP损伤12例,肩关节MR造影SPACE序列与常规二维序列对SLAP损伤的敏感度分别为83.33%(10/12)及91.67%(11/12),特异度分别为81.25%(13/16)及87.50%(14/16),准确度分别为82.14%(23/28)及89.29%(25/28)。SPACE序列与常规二维序列对SLAP损伤的诊断效能无明显统计学差异(P>0.05)。结论:肩关节MR造影中SPACE序列是评价SLAP损伤准确、可靠的影像学方法。Objective：To evaluate isotropic three dimensional fat suppressed turbo spin echo （SPACE）sequence in diagnosis of superior labrum anterior-to-posterior tears （SLAP lesions）of the shoulder in MR arthrography.Methods：3D-SPACE sequence and conventional two dimensional sequence were compared in patients with arthroscopically confirmed SLAP lesions of the shoulder.The sensitivity,specificity and accuracy of 3D-SPACE sequence and conventional two-dimensional sequence for detection of SLAP lesions were calculated,respectively.Results：Of the 12 cases of arthroscopically confirmed SLAP lesions,the sensitivity,specificity and accuracy of the 3D-SPACE and conventional sequence was 83.33% vs 91.67%,81.25% vs 87.50%and 82.14%vs 89.29%.There was no statistical difference between the two sequences in detecting SLAP lesions.Conclusion：3D-SPACE sequence in MR arthrography of shoulder is an accurate and reliable method to evaluate SLAP lesions.
