Cross-sectional studies of the lumbar spinal canal were performed by computerised tomography in asymptomatic subjects and in patients with myelographic and clinical findings suggestive of lumbar stenosis. In most cases stenosis was found to be developmental or combined in nature. Computerised tomography is a useful adjunct to myelography in the evaluation of lumbar stenosis as it enables an accurate assessment to be made of the type, degree and extent of narrowing of the vertebral canal.
对无症状受试者以及有脊髓造影和临床检查结果提示腰椎管狭窄的患者进行了腰椎管的横断面计算机断层扫描研究。在大多数情况下，发现狭窄本质上是发育性的或混合性的。计算机断层扫描在评估腰椎管狭窄方面是脊髓造影的有用辅助手段，因为它能够对椎管狭窄的类型、程度和范围进行准确评估。
