Blurring in spiral images can be caused by both field inhomogeneity and chemical shift. The method presented in this work addresses both by simultaneously separating fat-water signal and deblurring. A multi-peak fat model has been added to the previously presented algorithm, making the algorithm more robust while maintaining the same reconstruction time as the single-peak model.
