 Abstract: We evaluated the influences of the EEG gel on RF safety assessment of a 3T whole body scanner with a human subject located at a head landmark position. Our case study, which was performed assuming realistic conditions that may occur with commercially available equipment, provides evidence that the EEG gel “helmet” has an impact on head SAR during 3T MRI for a patient positioned at the head landmark position. A workaround for safe simultaneous EEG-MRI investigations might involve limiting the maximum transmit voltage at a lower level than that allowed by the scanner’s SAR supervision system (i.e. that for a given patient without EEG gel “helmet”).
