Dixon techniques are considered as one of the practical methods to suppress fat at a cost of additional scan time. Dual-echo Dixon techniques have recently shown great promise for very rapid imaging and robust separation with careful phase correction algorithms. In this work, we extend this dual-echo method using a dual flyback echo-planar imaging to further speed the acquisition of data. The new phase estimation method is proposed to include correction for a relative phase-direction shift of fat and water. We demonstrate in vivo water and fat separation for abdominal imaging.
