Body QSM relies on accurate magnetic field-mapping that accounts for the presence of fat and is robust to large background fields. This work proposes the application of a single-min-cut graph-cut-based pipeline aiming at accurate, non-smoothed and unwrapped field-mapping without the need for further computationally expensive or problematic voxel-wise fitting or unwrapping techniques. The used body QSM pipeline achieves higher accuracy in field-map and susceptibility values, which is demonstrated in a numerical phantom and in in-vivo spine datasets.
