3D echo planar spectroscopic imaging (EPSI) was implemented with a new dualband water and lipid suppression with integrated outer volume suppression. Compared to conventional CHESS and inversion recovery lipid suppression, water suppression with the dualband sequence was a factor of 2.65 better, while lipid suppression was 8.61 better. Metabolic images recreated with the dualband acqusition showed markedly reduced lipid contamination artifacts compared to conventional methods.
