肩关节常见病变:MRI诊断

MR imaging of the common shoulder abnormalities

肩关节常见病变主要为肩袖相关病变和肩关节不稳定。对于肩袖相关病变,肩关节MRI常规扫描可作为首选;对于肩关节不稳定和盂唇病变,则一般首选肩关节MRI造影进行评价。本文系统介绍肩峰下撞击综合征、肩袖变性、肩袖撕裂、肩关节前方不稳、上方盂唇前后向撕裂、肱二头肌长头腱相关病变、钙化性肌腱炎和滑囊炎、肩周炎的MRI表现。

Shoulder disorders mainly involve rotator cuff diseases and shoulder instability. For rotator cuff diseases, routine shoulder MR imaging as the first choice can solve most of the problems in practice. For shoulder instability and related glenoid labrum lesions, shoulder MR arthrography is the first selection for evaluation. The purpose of this article is to illustrate the MR appearances of several common shoulder abnormalities, including the sub-acromial shoulder impingement syndrome, rotator cuff degeneration, partial-thickness and full-thickness rotator cuff tears, anterior instability, superior labrum antero-posterior tears, biceps related disorders, calcific tendinitis and bursitis, and adhesive capsulitis.
