Functional MRI activation of individual interictal epileptiform spikes.

K Krakow1, D Messina, L Lemieux, J S Duncan, D R Fish.   

Abstract

We used spike-triggered functional MRI in a patient with localization-related epilepsy to determine whether individual (as opposed to averaged) focal interictal epileptiform discharges (spikes) were associated with hemodynamic changes detectable with blood oxygen level-dependent functional MRI (fMRI). It was found that 15 of 43 spikes (34.9%) were associated with significant focal fMRI activation. Single event-related fMRI of interictal spikes is feasible in selected patients, giving complementary information to that provided by averaged fMRI data. Copyright 2001 Academic Press.
