We studied the diagnostic accuracy of magnetic resonance imaging (MRI) and the possibility of its substitution for myelography in 78 patients with lumbar canal stenosis and/or disc herniation, who had myelography and MRI examination. The diagnostic results of the two methods were compared respectively with those of operation, showing no statistical significance (coincidence rate 88.5% vs 92.3%, P greater than 0.05). We conclude that MRI could clearly reveal the pathological changes and anatomical relations of lumbar structures without invasive and radioactive damages, and that with the improvement of operative technique, better understanding of images, and reduction of cost, MRI is likely to replace myelography in the future.
我们对78例患有腰椎管狭窄症和/或椎间盘突出症且已接受脊髓造影和磁共振成像（MRI）检查的患者，研究了MRI的诊断准确性及其替代脊髓造影的可能性。将这两种方法的诊断结果分别与手术结果进行比较，结果无统计学意义（符合率分别为88.5%和92.3%，P＞0.05）。我们得出结论，MRI能够清晰显示腰椎结构的病理变化和解剖关系，且无侵入性和放射性损害，并且随着手术技术的改进、对图像理解的加深以及成本的降低，MRI未来有可能取代脊髓造影。
