This commentary critiques a prior paper claiming that Brillouin precursors from 5G NR and other cellular systems could cause tissue damage deeper than the carrier-frequency penetration depth. It states that the original Brillouin precursor theory was based on nanosecond ultrawide-band RF pulses in water and that this…

This engineering study presents an optimization framework to design RF pulses for parallel transmission MRI with the goal of minimizing SAR. Using computer simulations of a 4-channel system, the authors report significant SAR reduction while maintaining excitation pattern quality and without increasing pulse…
