The impact of accurate imaging in the work-up of patients with glenohumeral instability is high. Results of imaging may directly influence the surgeon's strategy to perform an arthroscopic or open treatment for (recurrent) instability. Magnetic resonance (MR) imaging, and MR arthrography in particular, is the optimal technique to detect, localize and characterize injuries of the capsular-labrum complex. Besides TI-weighted sequences with fat suppression in axial, oblique sagital and coronal directions, an additional series in abduction and exoroation position is highly advocated. This ABER series optimally depicts abnormalities of the inferior capsular-labrum complex and partial undersurface tears of the spinatus tendons. Knowledge of different anatomical variants that may mimic labral tears and of variants of the classic Bankart lesion are useful in the analysis of shoulder MR arthrograms in patients with glenohumeral instability.
精确成像在盂肱关节不稳患者的检查中具有重要作用。成像结果可能直接影响外科医生针对（复发性）不稳采取关节镜或开放治疗的策略。磁共振（MR）成像，尤其是MR关节造影，是检测、定位和描述关节囊-盂唇复合体损伤的最佳技术。除了在轴向、斜矢状面和冠状面进行脂肪抑制的T1加权序列外，强烈推荐在外展和外旋位进行额外的序列成像。这个ABER序列能最佳地显示关节囊-盂唇复合体下部的异常以及冈下肌腱的部分下表面撕裂。了解可能模仿盂唇撕裂的不同解剖变异以及经典Bankart损伤的变异，对于分析盂肱关节不稳患者的肩部MR关节造影很有帮助。
