1. An MR data acquisition method for acquiring data D_φfat according to a steady-state pulse sequence specifying that the phase of an RE pulse is varied in order of 0, 1×φfat, 2×φfat, etc., wherein:
φfat=(2−TR/T_out+2×m)×π is established on the assumption that m denotes an integer equal to or larger than 0 and meets TR/(2×T_out)−1<m<TR/(2×T_out) where TR denotes a repetition time and T_out denotes the time during which spins in water and spins in fat are out of phase with each other due to chemical shifts.
