ABSTRACT:
A magnetic resonance imaging apparatus generates slice images by repeating, for a plurality of consecutive repetition times, transmitting an RF pulse to a plurality of slices and scanning the slices to acquire magnetic resonance signals generated therein, in multi-slice acquisition covering the sequential slices, the sequential slices including at least a first slice, a second slice, a third slice, and a fourth slice. In the first, second, third, and fourth slices, phases of the RF pulses are alternately reversed every consecutive repetition time, and the RF pulses are transmitted to the first, second, third, and fourth slices such that the phases of the RF pulses transmitted to the first and third slices are reversed from each other in each consecutive repetition time and such that the phases of the RF pulses transmitted to the second and fourth slices are reversed from each other in each consecutive repetition time.
