Late postictal residual perfusion abnormality in epileptogenic zone found on 6-hour postictal SPECT

Abstract

Late postictal hyperperfusion was found in more than half of the patients. Postictal perfusion abnormalities did not come back to the interictal phase 6 hours after ictus and these were identified on ictal/postictal 99mTc- HMPAO SPECT.
