ABSTRACT:
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 PS1for 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 ar1continuously alternate and the ratio of the magnitude HT1of the positive pulse PLP and the magnitude HT2of 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.
