Magnetic resonance imaging (MRI) has had an impressive impact on evaluation of degenerative diseases of the spine. Nevertheless, false negatives can occur on images involving lumbar discs. Degenerative disc diseases documented on discrography and/or pathology examination of the discs can go unrecognized. Likewise sensitivity for the detection of protruding discal hernias is not totally satisfactory (20% false negatives). Finally, a magnetic resonance image visualizing displacement of the disc is not specific (10 to 15% false positives); images showing protrusion or hernia can be seen in 30% of asymptomatic patients. Although MRI gives slightly more information than other imaging techniques, false images do exist. Moreover, the usefulness of MRI to demonstrate disc disease in case of a negative CT-scan remains to be demonstrated.
磁共振成像（MRI）对脊柱退行性疾病的评估产生了令人瞩目的影响。然而，在涉及腰椎间盘的图像上可能会出现假阴性结果。椎间盘造影和/或椎间盘病理检查中记录的椎间盘退行性疾病可能未被识别。同样，对于检测椎间盘突出症的敏感性也不完全令人满意（20%的假阴性）。最后，显示椎间盘移位的磁共振图像并不具有特异性（10%至15%的假阳性）；在30%的无症状患者中可以看到显示椎间盘突出或疝的图像。尽管MRI比其他成像技术提供的信息略多，但假图像确实存在。此外，在CT扫描结果为阴性的情况下，MRI用于显示椎间盘疾病的实用性仍有待证明。
