When pain or disability occurs after rotator cuff surgery, post-operative imaging is frequently performed. Post-operative complications and expected post-operative imaging findings in the shoulder are presented, with a focus on MRI, MR arthrography (MRA) and CT arthrography. MR and CT techniques are available to reduce image degradation secondary to surgical distortions of native anatomy and implant-related artefacts and to define complications after rotator cuff surgery. A useful approach to image the shoulder after surgery is the standard radiography, followed by MRI/MRA for patients with low "metal presence" and CT for patients who have a higher metal presence. However, for the assessment of patients who have undergone surgery for rotator cuff injuries, imaging findings should always be correlated with the clinical presentation because post-operative imaging abnormalities do not necessarily correlate with symptoms.
当肩袖手术后出现疼痛或功能障碍时，通常会进行术后影像学检查。本文介绍了肩部术后并发症及预期的术后影像学表现，重点是磁共振成像（MRI）、磁共振关节造影（MRA）和CT关节造影。MR和CT技术可用于减少因手术导致的正常解剖结构变形和植入物相关伪影而引起的图像质量下降，并明确肩袖手术后的并发症。术后肩部成像的一种有效方法是先进行标准X线摄影，对于“金属植入物存在量”低的患者，随后进行MRI/MRA检查，对于“金属植入物存在量”高的患者，则进行CT检查。然而，对于接受过肩袖损伤手术的患者进行评估时，影像学表现应始终与临床表现相关联，因为术后影像学异常不一定与症状相关。
