Comparison of Three Methods for Localizing Interictal Epileptiform Discharges with Magnetoencephalography

摘要

PurposeTo compare three methods of localizing the source of epileptiform activity recorded with magnetoencephalography (MEG): equivalent current dipole (ECD), minimum current estimate (MCE), and dynamic statistical parametric mapping (dSPM), and to evaluate the solutions by comparison with clinical symptoms and other electrophysiological and neuroradiological findings.
