Interpretation of MR imaging of the shoulder after instability repair can be significantly hampered by (susceptibility) artifacts and/or distortion of normal anatomy. Knowledge of the surgical procedures performed including the (ferromagnetic) materials used is important to adjust the imaging protocol, in order to reduce artifacts. MR arthrography is probably the optimal tool for assessment of postoperative capsular-labral structures and rotator cuff defects. More general postoperative complications can be determined or excluded using conventional fast spin echo sequences with or without fat-suppression.
不稳定修复术后肩部的磁共振成像（MR）解读可能会因（敏感性）伪影和/或正常解剖结构的变形而受到显著阻碍。了解所进行的手术操作，包括所使用的（铁磁性）材料，对于调整成像方案以减少伪影非常重要。磁共振关节造影可能是评估术后关节囊 - 盂唇结构和肩袖缺损的最佳工具。使用带有或不带有脂肪抑制的传统快速自旋回波序列可以确定或排除更常见的术后并发症。
