Neuroimaging of Epilepsy: EEG-fMRI in the Presurgical Evaluation of Focal Epilepsy

Abstract

Presurgical evaluation involves invasive investigation by stereoelectroencephalography (SEEG) performed after other routine exams (standard EEG, video-EEG, functional neuroimaging) to identify the interictal focus within the epileptogenic zone. The lesional area, instead, is nowadays studied with advanced MRI techniques developed to better identify the interictal focus.
