【摘要】 目的　探讨脊髓型颈椎病MRI表现及其临床意义。方法　对 78例脊髓型颈椎病手术前后MRI检查资料进行分析 ,并与ASIA评分改善率进行比较。结果　手术后临床症状均有不同程度的改善 ,脊髓受压程度及异常信号的形态与改善率呈显著负相关 (Ρ <0 .0 1 ) ,脊髓受压程度≥ 1 / 3 ,不论其信号是否异常 ,均预后较差。结论　MRI检查对脊髓型颈椎病的诊断有确定意义 ,对治疗方法选择及判断预后具有指导意义更多还原

【Abstract】 Objective To discover the appearance in MRI and clinical significance in cervical spondylotic myelopathy.Methods 78 cases were examined with MRI preoperation and postoperation, the data was analyzed and compared with the improvement rate of ASIA mark.Results All patients’ clinical symptoms were improved in different degree after operation. The spinal cord pressed degree and shape of abnormal signal have significant correlation with improvement rate(Ρ<0.01), if spinal cord pressed degree more than 1/3, the prognosis was bad in spite of the signal was normal or not. Conclusion The examination of MRI has definite significance to diagnose cervical spondylotic myelopathy, to select a perfect treatment method and estimate prognosis.更多还原
