HIGHLIGHTS
SUMMARY
The authors tuned the incomplete spectrum method (mask and band-limit) for QSM on a simulated dataset from the most recent QSM challenge and validated the QSM reconstruction results on brain images acquired in five healthy volunteers, comparing incomplete spectrum QSM to current state-of-the art-methods: FANSI, nonlinear dipole inversion, and conventional thresholded k-space division. Without additional regularization, incomplete spectrum QSM performs slightly better than direct QSM reconstruction methods such as thresholded kspace division (PSNR of 39.9 vs. 39.4 of TKD on a simulated dataset) and provides susceptibility values . . .
