What increases SAR in MRI?

SAR increases significantly with body size.

In our 2-dimensional model we found SAR proportional to A², the square of the body cross-sectional area. Because A = πr² (where r is the radius), our model predicts SAR proportional to r4.

What is the SAR limit in MRI?

4 W/kg

According to the U.S. Food and Drug Administration, the average SAR values are limited to 3 W/kg when the head is scanned for 10 min and to 4 W/kg when the body is scanned for 15 min7. In addition, the local SAR levels averaged over 10 g of tissue also need to be restricted even though a higher level is allowed.
