Magnetic resonance imaging apparatus and control method thereof

A magnetic resonance imaging apparatus comprising:

• an imaging unit that collects a nuclear magnetic resonance signal generated by an examination object, and acquires an image of the examination object;
• and an imaging controller that controls the imaging unit using a pulse sequence, wherein
• the pulse sequence includes a pulse sequence in which a plurality of imaging sequences that respectively acquire a plurality of images having different contrasts are combined, and one imaging sequence among the imaging sequences is an IR (inversion recovery) sequence including application of an inversion pulse and a signal acquisition sequence that collects a signal after an inversion time has elapsed from the application of the inversion pulse, and
• the imaging controller executes the IR sequence at a plurality of times with respect to a plurality of slices while shifting application timing of the inversion pulse of the IR sequence, and
• executes, between the inversion pulse of the IR sequence at a single time and the inversion pulse of the IR sequence at the next time, the imaging sequence different from the IR sequence with respect to a different slice from the slices to which the two inversion pulses have been applied.
