Multitransmit
MR corrects B1 inhomogeneity which lessens dielectric shading, and a more
uniform flip angle reduces focal SAR hot spots and allows for safe fetal MR
imaging at 3.0 T for brain anomalies, and using multitransmit MR with SENSE
allows for faster scan times and better signal to noise. We present 3 cases comparing 3.0T fetal MR
imaging with and without multitransmit to follow-up MR imaging in the
perinatal period to assess the accuracy, image quality, and clinical
feasibility of multitransmit MR imaging of the fetus at 3.0T
