Results of cervical myelography by the lumbar approach were compared with those of CT scan imaging after subarachnoid metrizamide by the lumbar route, in 16 patients operated upon for post-traumatic cervical spine lesions. Examination in each patient included the last four cervical and first thoracic roots on the injured side, making a total of 80 roots. Lesions detected by myelography and CT scanning are described, comparison of semiologic data with gross findings at operation showing poorer diagnostic accuracy for myelography (86%) than for myelography and a CT scan combined (97%). Sensitivity of the former varied between 70 and 90%, depending on whether doubtful forms were classed as normal or pathologic, but was lower than that of the CT scan (96%). This also applied to specificity (90% as against 96%) and diagnostic accuracy (86% to 90% as against 97%). Combining myelography with a CT scan after subarachnoid contrast injection provides complementary very precise data allowing improved therapeutic results.
对16例因创伤性颈椎损伤接受手术的患者，比较经腰椎途径进行颈椎脊髓造影的结果与经腰椎途径蛛网膜下腔注入甲泛葡胺后CT扫描成像的结果。对每位患者的检查包括损伤侧最后四个颈椎和第一胸椎神经根，共计80个神经根。描述了脊髓造影和CT扫描检测到的病变，将症状学数据与手术中的大体检查结果进行比较，结果显示脊髓造影的诊断准确性（86%）低于脊髓造影与CT扫描联合检查（97%）。前者的敏感性在70%至90%之间，取决于可疑形态被归类为正常还是病理状态，但低于CT扫描（96%）。这同样适用于特异性（分别为90%和96%）和诊断准确性（分别为86%至90%和97%）。蛛网膜下腔注入造影剂后将脊髓造影与CT扫描相结合可提供互补的非常精确的数据，从而改善治疗效果。
