Understanding the time course of RF deposition during typical clinical exams may yield useful information for defining testing guidelines and device performance criteria for implanted devices. Our objective was to retrospectively characterize and evaluate scanner reported SAR, B1-RMS, and sequence timing for patients undergoing routine cardiovascular or neurological MRI exams. Our analysis of clinical cardiac exams shows that the cumulative duration with SAR exposure >3.5 W/kg was 5-minutes of a 51-minute exam. Our analysis of clinical neurological exams shows that the cumulative duration with SAR exposure >2 W/kg was 10-minutes of a 30-minute exam.
