Detection of slightly increased signals in temporal lobe on periictal arterial spin labeling perfusion image for initial suspicion of temporal lobe epilepsy

Abstract

Introduction: Magnetic resonance (MR) perfusion imaging with arterial spin labeling (ASL) can easily detect periictal hyperperfusion accompanying epileptic seizures. Herein, we report two cases in which ASL performed immediately after a seizure was useful for the initial suspicion of temporal lobe epilepsy (TLE).
