The traditional chemical shift selective (CHESS) radiofrequency pulse is often ineffective in suppressing lipid within a large field of view (FOV) due to the presence of B0 inhomogeneity. In this abstract, we propose a new method to suppress lipid signal, Dual-Region Fat Saturation (DRFS). DRFS divides a scan region into multiple sub-regions, in which the shimming could then be applied independently. Volunteer results show that compared with CHESS, DRFS could achieve better and uniform fat suppression across entire FOV, which enable DRFS a much broader application.
