In the present study, we developed a method to combine a simple MRE technique with a fat/water separation method (Dixon method) based on a conventional gradient-echo type multi-echo MR sequence (GRE-MultiEcho-MRE). Because the proposed method used the GRE-multiecho MRE, it is possible to select shortest in-/opposed-phase TE in the 1st TE. Thus, the proposed method allows to increase signal-to-noise ratio of fat/water images.
