Scanning pregnant women in MRI systems operating at 3T has been a controversial issue with respect to RF exposure and RF field uniformity. The latter issue is solved by 3T parallel transmit systems. In this work, we demonstrate that, when scanning in normal operating mode, the simulated RF exposure increase is limited to an acceptable level when the real behaviour/constraints of the system are taken into account.
