| 目的 探讨肩关节MR双斜冠状位扫描对肩袖损伤的诊断价值。方法 对73例患者行前瞻性MR造影检查,除平行于冈上肌FS TSE T2WI斜冠状位扫描外,均加扫双斜冠状位,扫描方向分别平行于冈上肌腱和肱骨长轴。分析斜冠状位和双斜冠状位对肩关节解剖结构的显示效果及肩袖损伤的诊断结果。结果 双斜冠状位可以100%(73/73)将冈上肌、冈上肌腱以及肱骨长轴同时显示于一幅图像,斜冠状位不能同时显示(0/73)。双斜冠状位和斜冠状位对冈上肌腱评价结果一致性好(K=0.736)。双斜冠状位FS TSE T2WI诊断肩袖撕裂的敏感性和特异性分别为92.59%(25/27)、85.71%(18/21);斜冠状位FS TSE T2WI分别为70.37%(19/27)、85.71%(18/21),双斜冠状位诊断的敏感性优于斜冠状位(P<0.05)。结论 双斜冠状位能够清楚显示肩关节局部解剖结构,有利于对肩袖损伤做出准确判断。 |

| Objective To compare double oblique coronal FS TSE T2WI with oblique coronal FS TSE T2WI in diagnosing rotator cuff tears. Methods Seventy-three patients underwent matched double oblique coronal FS TSE T2WI with oblique coronal FS TSE T2WI. Oblique coronal FS TSE T2WI was parallel to the supraspinatus muscle and double oblique coronal FS TSE T2WI was parallel to the supraspinatus tendon and the long axis of the humerus. The detective effect of anatomy of shoulder joint and rotator cuff tears with two methods were analyzed. Results The visualization of the supraspinatus muscle, the supraspinatus tendon and the long axis of the humerus was 100% (73/73) on one image of double oblique coronal FS TSE T2WI, and none (0/73) on one image of oblique coronal FS TSE T2WI. In interpreting supraspinatus tendon signal and morphology the two methods showed good agreement with the Kappa value of 0.736. For detecting rotatof cuff tear, the sensitivity and specificity was 92.59% (25/27) and 85.71% (18/21) respectively for double oblique coronal FS TSE T2WI, while 70.37% (19/27) and 85.71% (18/21) respectively for oblique coronal FS TSE T2WI. The sensitivity of double oblique coronal FS TSE T2WI was higher than that of oblique coronal FS TSE T2WI (P<0.05). Conclusion Double oblique coronal FS TSE T2WI is helpful to the diagnosis of rotator cuff tears. |
