Dixon technique requires at least two images with different echo times, which increases TSE echo spacing and TR, and therefore prolongs total acquisition time. Slice acceleration may help improve imaging efficiency of TSE fat-water Dixon imaging. In this study, we develop a multiband slice accelerated TSE Dixon sequence and demonstrate the feasibility of SMS TSE Dixon acquisition for efficient T2-weighted fat-water imaging.
