摘　　要：目的：评价ＣＴ、ＭＲＩ对颈椎病的诊断价值。材料和方法：复习９０例颈椎病患者的术前和术后的ＣＴ和ＭＲＩ（８６例超低场，４例超导高场）影像，对其骨性结构和椎管内容物进行对比。结果：ＭＲＩ对颈椎间盘突出的显示优于ＣＴ。颈椎管狭窄的ＣＴ显示优于ＭＲＩ。后纵韧带骨化的ＣＴ显示优于ＭＲＩ。ＭＲＩ对脊髓受压程度的评估优于ＣＴ。ＣＴ能较好的评估术后减压范围和椎管扩大程度。ＭＲＩ在术后六个月可用于预测脊髓功能的恢复。结论：ＣＴ和ＭＲＩ对颈椎病的诊断和术后评估很在价值，二者可互为补充。Purpose:To evaluate the diagnostic value of CT and MRI for cervical spondylosis.Materials and Methods:The preoperative and postoperative CT and MR imaging of 90 patients with cervical spondylosis were veviewed.The characterstics of the bony structures and the contents of the spinal canal on CT and MRI(86 with ultralow and 4 with superconductive high field) were compared.Results:Prolapse of the intervertebral disc was visualized better by MRI than by CT.Visualization of stenosis of cervical spinal canal by CT was better than by MRI.Ossification of the posterior longitudinal ligament was shown better by CT than by MRI .CT was good for the assessment of the extent of decompression and the degree of enlargement of the spinal canal after operation.MRI was useful for the prediction of recovery of the function of the spinal cord 6 months after operation.Conclusion:CT and MRI are useful for the diagnosis and the postoperative evaluation of cervical spondylosis. They are complementary to each other.
