1. A magnetic resonance imaging apparatus comprising:

  • a memory; and

    a processor comprising processing circuitry, wherein the memory stores instructions, which when executed by the processor, cause the magnetic resonance imaging apparatus to perform operations comprising;

    a data collection unit that repetitively performs performing a tag mode of applying an RF wave to at least an upstream portion of an imaging area to label a fluid flown into the imaging area and, after a lapse of an inversion time from application of the RF wave, performing magnetic resonance data collection, while changing the inversion time;

    an image reconstruction unit that reconstructsreconstructing a plurality of tag images corresponding to a plurality of different inversion times based on magnetic resonance data collected in the tag mode;

    a reference image generation unit that generatesgenerating a reference image based on the plurality of the tag images; and

    a fluid image generation unit that generatesgenerating a subtraction image between each of the tag images and the reference image as a fluid image.
