To evaluate the efficacy of magnetic resonance (MR) arthrography in identification of the glenohumeral ligaments (GHLs) and to determine the location of abnormalities of the GHL, joint capsule, and labrum.
MR arthrograms were evaluated retrospectively in 46 patients with a history of shoulder instability, impingement syndrome, or pain of unknown cause. Imaging findings were correlated with surgical observations.
The superior, middle, and inferior GHLs were identified on MR arthrograms in 39 (85%), 39 (85%), and 42 (91%) of the 46 patients, respectively. In diagnosis of tears of the superior, middle, and inferior GHLs, MR arthrography had a sensitivity of 100%, 89%, and 88% and a specificity of 94%, 88%, and 100%, respectively.
Findings at MR arthrography can help accurate identification and demonstration of the integrity of the GHL and labrum and can help in staging of abnormalities. The large number of abnormalities depicted in the middle and inferior GHLs suggests that both might be important in the maintenance of glenohumeral joint congruity.
评估磁共振（MR）关节造影在识别盂肱韧带（GHL）方面的有效性，并确定GHL、关节囊和盂唇异常的位置。
回顾性评估46例有肩部不稳定、撞击综合征或不明原因疼痛病史患者的MR关节造影。影像学表现与手术观察结果相关。
46例患者中，分别有39例（85%）、39例（85%）和42例（91%）在MR关节造影上识别出上、中、下GHL。在诊断上、中、下GHL撕裂时，MR关节造影的敏感性分别为100%、89%和88%，特异性分别为94%、88%和100%。
MR关节造影的表现有助于准确识别和显示GHL和盂唇的完整性，并有助于对异常进行分期。中、下GHL中显示的大量异常表明两者在维持盂肱关节一致性方面可能都很重要。
