PROBLEM TO BE SOLVED: To provide a magnetic resonance imaging device in which setting of a pre-pulse can be easily and flexibly set.SOLUTION: A magnetic resonance imaging device 100 includes a lead-out unit 133a, and a sequence control unit 120. The lead-out unit 133a receives adjustment of signal values at collection timing of magnetic resonance signals by selection or non-selection of a plurality of types of tissue contained in the imaging area, and leads out application timing of pre-pulses to be applied before the collection of the magnetic resonance signals. The sequence control unit 120 applies the pre-pulse signals according to the application timing of pre-pulses, and collects the magnetic resonance signals in the imaging area.
