Computerized tomographic (CT) scanning of the fourth and fifth lumbar disc spaces with the GE CT/T8800 scanner followed by metrizamide myelography was obtained for 134 consecutive patients with suspected lumbar disc disease. There was an overall concordance rate of 85% between CT scanning and myelography. In those 52 patients treated by surgery, concordance between the CT and the myelogram was similar at 86.5%. Myelography and surgical findings were in agreement in 94.2% of cases, while CT findings and surgical finding agreed in 92.3% of cases. The authors' data indicate that the CT scan is as accurate as myelography in the diagnosis of lumbar disc disease. When the CT scan interpretation is supported by clinical findings, the myelogram may be eliminated in the preoperative patient. Myelography may be reserved for equivocal cases.
使用GE CT/T8800扫描仪对134例连续的疑似腰椎间盘疾病患者进行第四和第五腰椎间隙的计算机断层扫描（CT），随后进行甲泛葡胺脊髓造影。CT扫描和脊髓造影的总体符合率为85%。在52例接受手术治疗的患者中，CT与脊髓造影的符合率相似，为86.5%。脊髓造影与手术结果在94.2%的病例中一致，而CT结果与手术结果在92.3%的病例中一致。作者的数据表明，CT扫描在腰椎间盘疾病的诊断中与脊髓造影一样准确。当CT扫描结果得到临床发现的支持时，术前患者可能无需进行脊髓造影。脊髓造影可保留用于诊断不明确的病例。
