腔隙性脑梗死脑电地形图、脑电图与CT比较分析

Compared analysis of brain electrical activity mapping、EEG and CT in lacunar infarction

目的:观察腔隙性脑梗死(LI)脑电地形图(BEAM)、脑电图(EEG)改变的特点及临床诊断意义。方法:对60例LI行BEAM、EEG、CT及MRI检查,并与脑梗死组及正常组比较。结果:LI组BEAM阳性率77%,高于CT63%及EEG42%。主要变化为θ频带功率及δ/α、θ/α、δ+β/α+β比值增高,α频带功率低,BEAM异常主要在额区或顶、中央区。与对照组比较,LI做BEAM改变具有一定规律。结论:BEAM是诊断LI较敏感,并有一定的定位作用。

Objective：To observe the change of BEAM, EEG and CT in lacunar infarction, and their clinical diagnoses significance. Methods：60 cases patients with LI were examined with BEAM、EEG and Cr,compared with cerebral infarction group and common group respecfively.Results：The positive rate of BEAM in LI group was 77%, more than CT （63%） and EEG （42%）. Compared with controlled group, the change of BEAM for LI was regular. Conclusions： BEAM is sensitive in the diagnosis of lacunar infarction, it had determinate located role.
