Magnetic resonance imaging (MRI) is the preferred investigation for most spinal diseases and is increasingly requested for people with low back pain (LBP). However, determining the cause of back pain is complicated as it is often multifactorial and anatomical abnormalities are common in the spine and may not necessarily translate into clinical symptoms. Thus, national guidelines discourage the use of MRI in non-specific LBP and recommend reserving it for the investigation of severe or progressive neurological deficits or for those cases in which serious underlying pathology is suspected. It also has an acknowledged role in planning surgical management in cases of radiculopathy and spinal stenosis. This review summarises the indications for MRI in LBP and calls for improved education of patients and health professionals in the limitations of this investigation.
磁共振成像（MRI）是大多数脊柱疾病的首选检查方法，并且越来越多地用于腰痛（LBP）患者。然而，确定背痛的原因很复杂，因为它通常是多因素的，并且脊柱的解剖异常很常见，但不一定转化为临床症状。因此，国家指南不鼓励在非特异性 LBP 中使用 MRI，并建议将其保留用于严重或进行性神经功能缺损的调查，或怀疑有严重潜在病理的情况。它在计划神经根病和椎管狭窄症的手术治疗方面也具有公认的作用。这篇综述总结了 MRI 在 LBP 中的适应证，并呼吁加强对患者和卫生专业人员的教育，了解这项检查的局限性。
