摘　　要：目的探讨磁共振成像（ＭＲＩ）对癫痫病因诊断的意义。②方法随机选择２００例不同发作类型的癫痫病人进行颅脑ＭＲＩ检查，并与其中８７例颅脑ＣＴ检查结果进行比较。③结果ＭＲＩ的异常率为５８．５％，ＣＴ异常率仅为１１．５％（χ２＝５４．３，Ｐ＜０．００１）。７７例ＣＴ正常者，经ＭＲＩ检查有４５例病人呈异常改变。ＭＲＩ异常表现者中约１／３～１／２为脑萎缩性改变，１／４为脑血管病变。④结论ＭＲＩ对癫痫病因诊断具有一定的价值，其灵敏度明显高于ＣＴ．Objective\ To study the clinical significance of MRI in the etiologic diagnosis of epilepsy.\ Methods\ 200 various types of epilepsy patients were randomly selected and performed brain MRI examination. The results were compared with brain CT examination of 87 patient within the group.\ Results\ The abnormality rate of MRI was 58.5%, of CT was 11.5% ( χ 2=54.3,P<0.001 ). Of the 77 patients with normal CT results, 45 patients showed abnormality by MRI. There were 1/3- 1/2 patients having encephalatrophy and 1/4 patients having cerebrovascular disease.\ Conclusion\ MRI had clinical significance in etiologic diagnosis of epilepsy. The sensitivity of MRI in diagnosing epilepsy was higher than that of CT.
