In this abstract, we proposed to use parallel imaging method to remove the fat residue in EPI applications. In EPI, fat is shifted along the phase encoding direction and can be treated as another simultaneously exited slice with controlled aliasing together with the water image. By applying SENSE, water and fat residue can be effectively separated. We have presented this simple method to separate water and fat in EPI images and successfully applied it to remove fat residue in the brain and abdomen fat-suppressed EPI and DW-EPI images.
