Neuroimaging in epilepsy now incudes magnetic resonance imaging, posit
ron emission tomography (PET), single-photon emission tomography (SPEC
T), magnetoencephalography, and magnetic resonance spectroscopy. Recen
t advances in neuroimaging include improved rates of detection of lesi
ons on structural imaging using quantitative methods, identification o
f metabolic patterns on functional imaging with PET, and recognition o
f the value of ictal SPECT in seizure localization.
