摘要
目的：探讨脊髓型颈椎病手术前后的ＭＲＩ改变与临床意义。方法：１８例脊髓型颈椎病患者于手术前后均行ＭＲＩ检查。观察脊髓的形态学及信号改变与临床疗效之间的关系。结果：术前ＭＲＩ主要特点是受累节段椎间隙变窄，椎体后缘骨赘形成，椎间盘变性，Ｔ１加权呈低信号，颈髓受压移位、形态改变；Ｔ２加权信号异常变化。术后ＭＲＩ主要表现是植骨块稳定，颈髓矢状径及形态有不同程度恢复。结论：手术前后的ＭＲＩ改变可直接反映颈髓的病变程度及预后。ＭＲＩ作为对颈髓病变的诊断。
Aim:To clarify the Significance of the preoperative and postoperative magnetic resonance imaging(MRI)changes in cervical spondylotic myelopathy patients.Methods:18 patients with cervical spondylotic myelopathy were examined with MRI in preoperation and postoperation.Results:18 patients showed that MRI clearly delineated the degenerative changes of discs,the compression atrophy and the areas abnormal changes of focal compression of spinal cord.Conclusions:MRI is valuable for the diagnosis,treatment and prognosis of spinal cord.
