In this work, we investigated the application of B0 shimming with constraints, in order to accomplish an intrinsic fat suppression during 2D EPI-based pulses. For this purpose, we simulated shimming in an ROI confined to part of the abdomen. Our initial results along with the experimental tests demonstrate the possibility for such a fat suppression method. However, the residual inhomogeneity in the main excitation ROI might become very substantial, if the restriction area for fat frequencies is too narrow.
