Possible temperature increase due to RF exposure during MRI scan of pregnant women can be critical for the fetus. In this study, we perform electromagnetic and temperature simulations using different pregnant women models with different postures. We assess the variability of in-utero RF induced heating in a 3T birdcage coil for different models generated by segmenting structural MR images.
