A silent 3D multi-echo gradient-echo pulse
sequence is developed for quantitative susceptibility mapping (QSM). The new,
silent sequence is compared to the standard acquisition and gives comparable susceptibility
values. The silent acquisition gives the benefit of patient comfort and
workflow ease at some cost to SNR and acquisition time.
