摘要
目的探讨脊髓型颈椎病的MRI改变与患者预后的相关性。材料和方法将71例脊髓型颈椎病患者,根据T1WI/T2WI的信号变化分为等/等、等/高、低/高及信号改变在受压部位以外四组,进行手术前后随访,比较改善率。结果手术后临床症状均有不同程度的改善,脊髓的受压程度与改善率呈负相关(P<0.01),等/等信号组预后较好,低/高信号组预后较差。结论MRI检查对脊髓型颈椎病的预后判断具有指导意义。
Purpose:To evaluate the relationship between the MRI changes and the prognosis of patients with cerˉvical spondylotic myelopathy.Materials and Methods:71patients with cervical spondylotic myelopathy were divided into four groups according to the spinal cord signal intensity changes on T 1 WI/T 2 WI:norˉmal/normal,normal/high-signal intensity changes,low-signal/high-signal intensity changes and sigˉnal intensity changes beyond the site of compression.Results:All patients'clinical symptoms were imˉproved in different degree after operation.The spinal cord compressed degree had significant correlation with improvement rate(P<0.01),the prognosis was better in the normal/normal signal intensity changes,and bad in low-signal/high-signal intensity changes.Conclusion:The examination of MRI had significance to estimate clinical prognosis.
