Abstract:
:This study was carried out to evaluate Synthetic Aperture Magnetometry-kurtosis (SAM(g(2))), a spatially filtered source localization technique in magnetoencephalography (MEG), for identification of epileptogenic areas of focal cortical dysplasia (FCD). Three children with FCD were investigated to localize the ictal onset zone (IOZ). All patients subsequently had extraoperative electrocorticography (ECoG) for intractable epilepsy and surgical resection. SAM(g(2)) analysis showed overlapping of interictal MEG spike sources with the IOZ on ECoG in all children. We recommend MEG-SAM(g(2)) and MEG interictal spike source localization in patients with epileptogenic FCD.

杂志文章abstract:INTRODUCTION:Prior research has shown that people with epilepsy are at risk for a poorer health-related quality of life (HRQOL). However, patients differ greatly in how well they adjust to their epilepsy. To better understand these differences, the present study examined the role of personality. More specifically, we e...
