MRI is rapidly becoming the imaging modality of choice in the diagnostic assessment of patients with persistent or recurrent symptoms following spinal surgery. It displays the normal postoperative findings as well as most causes of FBSS. MRI can differentiate persistent or recurrent disk herniation from postoperative scar formation with a greater degree of confidence than other imaging modalities. MRI can determine clinically important functional instability when CT and conventional radiography are inconclusive. This can be particularly helpful in evaluating the patient with multiple lumbar surgeries. MRI can also determine the presence of other causes of the FBSS such as lateral spinal stenosis, arachnoiditis, fat graft compression on the thecal sac, and presence of postoperative hematoma or postoperative infection.
在对脊柱手术后仍有持续或复发症状的患者进行诊断评估时，磁共振成像（MRI）正迅速成为首选的成像方式。它能显示术后的正常表现以及大多数腰椎手术失败综合征（FBSS）的病因。与其他成像方式相比，MRI能够更有把握地区分持续性或复发性椎间盘突出与术后瘢痕形成。当CT和传统放射学检查结果不明确时，MRI能够确定具有临床意义的功能不稳。这在评估接受多次腰椎手术的患者时可能特别有帮助。MRI还能够确定FBSS的其他病因，如侧隐窝狭窄、蛛网膜炎、脂肪移植对硬膜囊的压迫，以及术后血肿或术后感染的存在。
