Utility of Ictal Magnetoencephalography for Identifying Seizure Onset Zone
In a review of 377 magnetoencephalography (MEG) studies in epilepsy patients undergoing presurgical workup, 44 patients were found to have one or more seizures during routine recordings, lasting up to a mean of 51.2 minutes. Ictal MEG provided unique localizing data in about one-third of patients. For patients with frequent seizures or reliably induced seizures, MEG may be a useful supplemental tool for medically refractory epilepsy patients undergoing presurgical evaluation.
