Abstract:
Objective To analyze the value of video electroencephalogram (VEEG) and brain imaging in diagnosis of epilepsy.Methods The routine electroencephalogram (REEG),VEEG,brain MRI and CT results of 112 patients with epilepsy were compared.Results In 112 epilepsy patients,39 patients (34.8％) showed epileptic focus in REEG,and 87 patients (77.7％) showed epileptic focus in VEEG.Seventy patients (62.5％) revealed lesions by brain MRI examination,37 patients (33.0％) revealed lesions by brain CT examination.Focal abnormal rate of brain MRI examination had significant difference between focal discharge patients and diffuse discharge patients [58.9％ (43/73) vs.21.4％ (3/14)] (P ＜0.01).Positioning accuracy had significant difference between temporal lobe discharge and outside temporal lobe discharge [53.1％(17/32) vs.26.8％(11/41)](P＜ 0.01).Conclusions Rate of epileptic discharge found by VEEG is significantly higher than that by REEG.Brain MRI displays epileptic discharge lesions better than brain CT,and MPd is an important method to find epileptic focus localization.It has a certain relationship between these two methods.It has a very important significance to combine with both methods in diagnosis of epilepsy.
