1. A magnetic resonance imaging apparatus comprising:

  • a blood flow velocity acquiring unit that acquires a flow velocity of the blood flow of an object;

    an imaging condition setting unit configured to set on the basis of the flow velocity of the blood flow acquired by the blood flow velocity acquiring unit, at least one of (a) a transmitting phase of a transmitted exciting pulse, (b) a transmitting phase of a refocusing pulse, (c) a shift amount of the relative phase difference between the transmitted exciting phase and the refocusing pulse, and (d) an intensity of a gradient pulse in a readout direction as an imaging condition;

    said capturing condition setting unit is configured to perform the setting such that (i) intensities of magnetic resonance signals generated from a vein in a diastole and a systole of the cardiac muscle of the object are equal to each other, and (ii) the difference between intensities of magnetic resonance signals generated from an artery in a diastole and a systole of the cardiac muscle of the object increases; and

    a blood flow image capturing unit that creates a blood flow image of the object by performing an imaging scan on the basis of the imaging condition set by the imaging condition setting unit.
