Localizing seizure-onset zone from ictal electroencephalography (EEG) is the gold standard for detecting the epileptogenic zone (EZ), combined with assessing the epileptogenic lesions (e.g., MRI), irritative zones (e.g., interictal spikes, MEG), and functional deficit zones (e.g., FDG-PET, SPECT).
MEG, magnetoencephalography; MRI, magnetic resonance imaging; FDG-PET, fluorodeoxyglucose-positron emission tomography; SPECT, single-photon emission computerized tomography
