A number of device manufacturers report non-standard SAR limits as conditions for the safe scanning of patients with these devices implanted. In this work we compared how the SAR was displayed on the console and what evidence of SAR levels were recorded in the DICOM header for MRI systems from three major vendors. We investigated possibilities for creating low SAR protocols that are robust in terms of never exceeding a defined non-standard SAR limit in any case.
