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.
