210例癫患者脑电图及头颅磁共振成像检查结果分析

Analysis of Electroencephalogram and Magnetic Resonance Imaging Results in 210 Cases of Patients with Epilepsy

目的探讨头颅磁共振成像(MRI)和脑电图在癫诊断中的应用以及两者的相关性。方法回顾性分析210例中国宁夏回族自治区农村癫患者的一般病例资料、脑电图及头颅MRI检查结果。结果 210例癫患者中,头颅MRI发现异常139/210例(66.2%),以软化灶、脱髓鞘病变为主。脑电图异常180/210例(85.7%),其中轻度异常66/180例(36.7%),中度异常为106/180例(58.9%),重度异常为8/180例(4.4%)。脑电图异常组(68.9%)患者的头颅MRI异常发现率明显高于脑电图正常组患者(50.0%),差异有统计学意义(P=0.043)。结论脑电图是确诊癫和指导治疗的有利依据,头颅MRI为癫病因诊断的首选影像学检查手段,两者有一定关联。

Aim To analyze the application of head magnetic resonance imaging （MRI） and electroencephalogram （EEG） in the diagnosis of epilepsy and explore their correlation. Methods The characteristics, EEG, and radiological data of 210 patients with epilepy in nural Ningxia were retrospectively analyzed. Results 139 cases were found abnormal brain MRI （139/210 cases, 66.2%）. Most of them were encephalomalacia and demyelination. 180 cases were found abnormal EEG（180/210 cases, 85.7%）. Among them, 58.9% were widely moderate abnormal. MRI abnormal rate in patients with abnormal EEG（68.9%） was higher than that in patients with normal EEG （50.0%）. The difference was statistically significant （P=0.043）. Conclusion EEG is vital for diagnosis and treatment for epilepsy. MR/should be the first imaging examination for the diagnosis of the etiology of epilepsy. There is a certain relation between EEG and MRI.
