Related to specific absorption rate: Maximum Permissible Exposure

specific absorption rate

An MRI term for the radio frequency (RF) energy absorbed per unit of mass of an object, measured in watts per kilogram (W/kg). The greatest concern with RF exposure is the potential for heating patients’ tissues, which is directly related to the specific absorption rate.
