脊髓造影加CT与MRI对颈椎病及后纵韧带骨化诊断价值的比较

Comparison CTM to contrast MRI the value of diagnosis for cervical spondylosis and OPLL

本文通过对３８例脊髓型颈椎病术前脊髓造影加ＣＴ和ＭＲＩ结果的比较分析，就此二种检查方法的诊断价值做出了评价。结果提示在显示颈椎间盘突出方面，ＭＲＩ明显优于脊髓造影加ＣＴ；在显示颈椎骨质增生、ＯＰＬＬ、颈神经很受压方面，ＭＲＩ不如脊髓造影加ＣＴ；在显示颈椎管狭窄蛛网膜下腔和脊髓受压方面，ＭＲＩ和脊髓造影加ＣＴ无明显差异。

The preoperative diagnostic value of MRI and CTM have been appraised for degenerative diseases of cervical spine and OPLL of 38 patients with cervical spondylotic myelopathy. It has been demonstrated that the MRI is more sensitivity than CTM in the disc herniation (P<0. 001). It was showing bony spurs, OPLL and nervous roots constricated, MRI was worse than CTM (P<0. 001). In showing spinal stensis, suberachnoid space and spinal cord contricted, there is no difference between the two methods.
