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 di-agnosis 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-dimen-sional sequence for detection of SLAP lesions were calculated,respectively.Results:Of the 12 cases of arthroscopically con-firmed 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 de-tecting SLAP lesions.Conclusion:3D-SPACE sequence in MR arthrography of shoulder is an accurate and reliable method to evaluate SLAP lesions.
