"The International Electrotechnical Commission (IEC) and the USA's Food and Drug Administration (FDA) limit the amount of energy absorbed by the body for a single MRI examination to 1°C/kg 1,2. In general, to prevent a rise in body temperature >1°C, the body cannot be exposed to more than 4 watts per kilogram. For example, high SAR sequences of a 3 T MRI deposits ~1.9-2.5 W/kg 3."
