Synopsis

Keywords: Safety, SafetyNumerical investigations on the safety of patient assistants exposed to a 1.2T open MRI are performed at different poses of patient assistants (including wearing latex gloves), because current regulations are concerned with only patient RF safety. Compared with the patient, up to 29.8% of the patient 10-gram SAR was observed in the patient assistant. To prevent possible RF hazards of a patient assistant during MRI scans, certain clauses regarding the patient assistant’s poses or wearing gloves must be added to the existing MRI screening forms.
