Eighty patients with operatively proven lumbar disc herniation or lumbar spondylosis were preoperatively evaluated with metrizamide myelography followed by metrizamide-enhanced computed tomography (CT). The x-ray films were reviewed without knowledge of the operative findings, and the patients were subdivided into those with disc extrusions, spondylosis, or recurrent abnormalities. For the group as a whole, CT was correct in 82% and myelography was correct in 77%. Both CT and myelography together were accurate in 91%, a significant improvement (P less than 0.02). The authors conclude that, if both studies are performed, the percentage of cases correctly diagnosed is increased. Therefore, both metrizamide myelography and metrizamide-enhanced CT should be obtained in selected cases. A review of the literature is included.
80例经手术证实患有腰椎间盘突出症或腰椎病的患者，术前先接受甲泛葡胺脊髓造影检查，随后进行甲泛葡胺增强计算机断层扫描（CT）。在不知手术结果的情况下复查X线片，并将患者分为椎间盘突出、腰椎病或复发性异常患者。就整个组而言，CT诊断正确的占82%，脊髓造影诊断正确的占77%。CT和脊髓造影两者联合诊断正确的占91%，有显著改善（P小于0.02）。作者得出结论，如果两项检查都进行，正确诊断的病例百分比会增加。因此，在某些选定病例中应同时进行甲泛葡胺脊髓造影和甲泛葡胺增强CT检查。文中还包括了文献综述。
