Summary
Objective
Interictal [18F]fluorodeoxyglucose–positron emission tomography (FDG-PET) is used in the presurgical evaluation of patients with drug-resistant focal epilepsy. We aimed at clarifying its relationships with ictal high-frequency oscillations (iHFOs) shown to be a relevant marker of the seizure-onset zone.
Methods
We studied the correlation between FDG-PET and epileptogenicity maps in an unselected series of 37 successive patients having been explored with stereo-electroencephalography (SEEG).
Results
At the group level, we found a significant correlation between iHFOs and FDG-PET interictal hypometabolism only ...
