Interictal single-photon emission computed tomography (SPECT) studies have demonstrated that there is hypoperfusion within the extra-temporal structures besides to the temporal lobe in mesial temporal lobe epilepsy (mTLE), which contributes to the proposal of concept of the mesial temporal lobe epilepsy network [1]. The purpose of this study was to determine the feasibility of detecting perfusion abnormalities in mTLE using arterial spin labeling (ASL)-based MRI, which is a noninvasive method for calculating regional cerebral blood flow (rCBF).
