We evaluated six different phase unwrapping algorithms for their use in QSM in the abdomen. Therefor a numerical phantom of the abdomen was simulated using a forward model. The resulting unwrapped phases and susceptibility maps were compared with the ground truth and root mean squared error maps were calculated. Results suggest that the “graph-cuts” algorithms should be used for phase unwrapping in the abdomen, as it was the most robust around the lungs and bones and further showed the smallest difference to the ground truth susceptibility.
