目的 探讨冻结肩的磁共振成像 (magnetic resonance imaging, MRI)表 现，提高对冻结肩的诊断水平。方法 回 顾性分析我院确诊为冻结肩的81例(81 人)患者的MRI影像资料，观察记录关节 囊水肿征(包括前上、前下、后下、后上 部及大范围水肿)、关节囊增厚征、肩袖 间隙水肿征、喙突下滑囊积液征、喙肱 韧带增厚/水肿征等征象的检出率，总结 其影像特点。结果 关节囊水肿征的检出 率为96.3%，其中前上部、前下部、后下 部、后上部及大范围水肿的检出率分别为 33.3%、87.7%、59.3%、56.8%及80.2%； 关节囊增厚征检出率为59.3%(48例肩袖间 隙水肿征检出率为69.1%、喙突下滑囊积 液征检出率为40.7%、喙肱韧带水肿征检 出率为24.7%。结论 关节囊水肿征、肩袖 间隙水肿征及关节囊征增厚征在冻结肩中 出现率较高，关节囊水肿尤以前下部多 见；喙肱韧带水肿征检出率较低。

Objective To study the magnetic resonance imaging findings of frozen shoulder so as to improve the diagnostic level of it. Methods A retrospective analysis of MR images was performed in 81 cases (81 patients) with clinically confirmed frozen shoulder in our hospital. The joint capsule edema sign (including anterior-superior, anterior-inferior, posterior-inferior, posterior-superior and wide range of edema), joint capsule thickening sign, rotator cuff interval edema sign, hydrops of capsule under coracoid process sign, coracohumeral ligament thickening/edema sign were observed and recorded and the features were summed up. Results The detection rate of joint capsule edema sign was 96.3%, with 33.3%, 87.7%, 59.3%, 56.8% and 80.2% of anterior-superior, anteriorinferior, posterior-inferior, posterior-superior and wide range of edema. The detection rate of joint capsule thickening sign was 59.3%. The detection rate of rotator cuff interval edema sign was 69.1%. The detection rate of hydrops of capsule under coracoid process sign was 40.7% and the detection rare of coracohumeral ligament thickening/edema sign was 24.7%. Conclusion Joint capsule edema sign, rotator cuff interval edema sign and joint capsule thickening sign had a higer detection rate in frozen shoulder and anterior-inferior edema edema was especially common within joint capsule edema sign. Coracohumeral ligament thickening/edema sign had a low detection rate in frozen shoulder.
