Phase imaging has been demonstrated to achieve a good contrast between and within brain tissues at 7T . However, phase imaging suffers from a non-local contrast variation which can be overcome by calculating the underlying magnetic susceptibility maps . As this problem is ill-posed, many regularization methods have been proposed over the past years [2-5]. In this abstract we do a thorough comparison of some of these methods,  and , focus on the impact of the prior information on the reconstructed susceptibility maps and propose a method to evaluate the quality of the susceptibility reconstruction in the absence of a ground truth.
