Body-QSM remains challenging for various reasons including, (a) the incomplete separation of background- and local-fields included by assumed approximations,(b) incorrect modeling at low-SNR-voxels included by linear modeling of the inverse problem and (c) streaking artifacts. A recently developed total-field-inversion (TFI) QSM method that directly estimates the susceptibility from multi-echo data showed significant alleviation of the above artifacts. However, the original TFI method can only be applied to regions with one species. This work proposes a QSM method that directly estimates susceptibility from multi-echo data in regions where water and fat are present and demonstrates its advantages over former proposed methods.
