癫癎患者脑电图癎样放电起源区域与头颅MRI病变部位的相关性研究

Study of Relationship between the Origin of Epileptiform Discharge on EEG and the Focus on MRI in Epilepsy Patients

目的:探讨脑电图(EEG)癎样放电起源区域与头颅MRI病变部位的关系。方法:回顾性总结221例因癫癎症状就诊患者的病史和EEG特点,分析其影像学改变,利用描述性分析及Logistic回归分析等统计学方法进行分析。结果:221例癫癎患者EEG出现癎样放电波127例(57.47%),局灶懒波51例(23.07%),背景节律改变39例(17.65%),前额部高波幅δ节律44例(19.91%),局部高波幅慢活动13例(5.88%)。头颅EEG癎样放电波出现区域与头颅MRI发现病变部位相吻合者101/127例(79.53%),与头颅MRI发现病变部位异侧的为8/1 27例(6.30%)。Logistic回归分析结果显示大部分EEG癎样放电波起源区域与头颅MRI病变部位有着较好的对应关系。结论:癎样放电波形起源区域与头颅MRI病变部位有着较好的吻合程度。

Aim： To investigate the relationship between the origin of the epileptiform discharge and the position of focus on MRI. Methods： The medical history, EEG characters of 221 patients with epilepsy symptoms were reviewed and analyzed by descriptive analysis and logistic regression analysis, combining the imaging changes. Results： There were 127/221（57.47%） patients with epileptiform discharge on EEG, 51/221 （23.07%） patients with focal idle wave, 39/221（17.65%） patients with background rhythm change, 44/221 （19.91%） patients with frontal high amplitude and rhythm, 13/221（5.88%） patients with focal high amplitude slow rhythm. Epileptiform discharge originated from the same side of focus in 101/127 patients（79.53%）. Epileptiform discharge originated from the other side of focus in 8/127（6.30%）. The result of logistic regression analysis shows that the origin of epileptiform discharge corresponded well with the position of focus on MRI. Conclusion： The origin of epileptiform discharge coincided well with the position of focus on MRI.
