The ability to detect and categorize SLAP (Superior Labrum Anterior to Posterior) lesions of the scapular labrum is of practical importance to the orthopedic surgeon and the radiologist. The aim of this study, performed on cadaveric shoulders, was to determine whether CT arthrography or MR arthrography is able to show normal anatomical variation of the glenoid labrum and detect labral abnormalities. CT arthrography, MR arthrography followed by anatomical dissection were performed on twenty three fresh frozen cadaveric shoulders and analysed by a radiologist and two orthopaedic surgeons. As Gadolinium intra-articular injection is not allowed in France, we used an iodinated contrast media for both MR arthrography and CT arthrography. In this study, the sensitivity of MR arthrography seemed higher than CT arthrography (respectively 4 and 3 labral lesions diagnosed out of five), although no significant statistical conclusions can be made due to the small number of cases. In conclusion, under such specific conditions, MR arthrography seems to be the method of choice for the detection and classification of labral lesions.
肩胛盂唇上从前到后的（SLAP）损伤的检测和分类能力，对于骨科医生和放射科医生具有实际重要性。本研究在尸体肩部上进行，目的是确定CT关节造影或MR关节造影是否能够显示盂唇的正常解剖变异并检测唇异常。对23个新鲜冷冻尸体肩部进行了CT关节造影、MR关节造影，随后进行解剖，并由一名放射科医生和两名骨科医生进行分析。由于在法国不允许关节内注射钆，我们在MR关节造影和CT关节造影中均使用了碘化造影剂。在本研究中，MR关节造影的敏感性似乎高于CT关节造影（分别从5例中诊断出4例和3例唇损伤），尽管由于病例数量少无法得出显著的统计学结论。总之，在这种特定条件下，MR关节造影似乎是检测和分类唇损伤的首选方法。
