We report the feasibility to record in a single session
combined EEG-PET, MRI, EEG-fMRI and ESI using
high-density EEG and a PET-MRI hybrid scanner. This
whole multimodal procedure could be performed in less
than two hours with good patient comfort. This
single-session quadrimodal imaging could be of great
interest for epilepsy presurgical mapping and may
replace four separated exams usually performed to
identify the epileptic focus. It may improve
significantly the patient workflow in epilepsy unit and
reduce the cost of presurgical epilepsy evaluations.
