We have proposed that a
QSM reconstruction method combining an iterative least square minimization and adaptive edge-preserving filtering could
generate high-quality susceptibility maps. In this study, maps calculated by
the proposed method were compared qualitatively and quantitatively with those
calculated by COSMOS (a calculation of susceptibility
through multiple-orientation sampling) in healthy volunteers. The
results from human brain experiments showed good agreement with COSMOS. The
proposed QSM reconstruction of single orientation sampling is useful for generating a high-quality susceptibility
map of the human brain.
