Abstract

This letter uses data from the literature to estimate the temperature rise in the fetus due to RF deposition within normal SAR limits for the pregnant woman. The results suggest that caution should be exercised when performing fetal MRI at high SAR levels until further data are available. It makes several recommendations related to fetal MRI and fetal SAR modelling.
