Safety and imaging performance of two‐channel RF shimming for fetal MRI at 3T
PURPOSE: This study investigates whether two-channel radiofrequency (RF) shimming can improve imaging without increasing specific absorption rate (SAR) for fetal MRI at 3T. METHODS: Transmit field ( B1+ ) average and variation in the fetus was simulated in seven numerical pregnant body models. Safet...
