With the emergence of B1+RMS as a more precise RF exposure metric than SAR, implantable device manufacturers have begun MR Conditional labeling to fixed B1+RMS levels, in addition to SAR labeling. We previously characterized the relationship between wbSAR-scaled and B1+RMS-scaled RF heating of cardiac pacing leads in the context of 3T Normal Operating Mode and First Level Controlled Mode MRI exposure [1]. In this study, we extend the analysis to 1.5T.
