Manifestation of magnetic source imaging in patients with hippocampal sclerosis temporal lobe epilepsy

Objective To evaluate the epileptic focus localization value of MSI in patients with hippocampal sclerosis temporal lobe epilepsy.Method MSI examination was performed in 15 patients with hippocampal sclerosis temporal lobe epilepsy.The results was compared with electroencephalography(EEG),video-electroencephalography(V-EEG),intro-operative electroencephalography(ECoG) and MRI 12 of them were treated with surgery,3 of them were treated with gamma knife.Results Single epileptic foci were determined by MEG in all of the patients.11 of them were in medial temporal lobe and 3 of them were in lateral temporal lobe.ECoG were performed in 12 patients during operation,and results were completely accord with MSI.Conclusion MSI localization of epileptic focus in patients with hippocampal sclerosis temporal lobe epilepsy is precise,and it can direct the advanced clinical treatment.
