A method and apparatus for mitigating limitations on spatial selectivity and frequency selectivity in space- and frequency-selectively generating magnetic resonance signals, when applying a first pulse sequence PS1 for suppressing a frequency component of fat in a predefined slice in a region to be examined of a subject by an RF coil section and a gradient coil section, gradient magnetic field pulses a in which a positive pulse PLP and a negative pulse PLN having the same area ar1 continuously alternate and the ratio of the magnitude HT1 of the positive pulse PLP and the magnitude HT2 of the negative pulse is HT1:HT2=½ are applied by the gradient coil section, and pulses of RF waves for space and frequency selection are applied by the RF coil section simultaneously with the positive pulses PLP.
