MRI with intravenous contrast has recently become the imaging modality of choice in the evaluation of patients developing recurrent back pain or symptoms following laminectomy and/or discectomy. The normal postoperative appearance is important to recognize because a number of changes occur normally throughout the healing period. The difference between epidural scar and recurrent disc herniation can usually be determined on MRI. Postoperative fluid collections may also develop. Disc space infection, although uncommon, is a critical diagnosis, but can be confused with degenerative end plate changes. Arachnoiditis and spinal stenosis also show characteristic imaging findings.
静脉注射造影剂的磁共振成像（MRI）最近已成为评估接受椎板切除术和/或椎间盘切除术后出现复发性背痛或症状患者的首选成像方式。认识术后的正常表现很重要，因为在整个愈合过程中通常会发生一些变化。硬膜外瘢痕和复发性椎间盘突出之间的差异通常可以通过MRI来确定。术后也可能会出现液体积聚。椎间盘间隙感染虽然不常见，但却是关键诊断，但可能与退行性终板改变相混淆。蛛网膜炎和椎管狭窄也有特征性的影像学表现。
