方法：报告了３６例临床诊断为腰突症患者，均先行脊髓造影后又行ＣＴＭ检查。结果：经手术证实，脊髓造影诊断符合率为８７５％，ＣＴＭ诊断符合率为９６９％。结论：故ＣＴＭ检查诊断准确率较脊髓造影高，且ＣＴＭ对于腰椎间盘膨出或小关节突肥大合并侧隐窝狭窄也有较高的诊断价值。 Methods: 36 cases of patients with clinical diagnosis of lumbar disc herniation were reported, all underwent myelography after CTM. Results: The operation confirmed that the coincidence rate of myelography was 875% and the coincidence rate of CTM was 969%. Conclusion: CTM examination is more accurate than myelography, and CTM is of high diagnostic value for lumbar disc herniation or facet joint hypertrophy with lateral recess stenosis.
