- 摘要：
PROBLEM TO BE SOLVED: To provide a magnetic resonance imaging apparatus and a method of setting capturing condition in a magnetic resonance imaging apparatus, by which signals from a blood flow to be captured can be captured with a higher signal intensity and clearer blood flow images can be extracted in a non-contrast MRA.
SOLUTION: A magnetic resonance imaging apparatus includes a blood flow velocity acquiring unit 46 that acquires a flow velocity of the blood flow of an object, a capturing condition setting unit 45 that, on the basis of the flow velocity of the blood flow acquired by the blood flow velocity acquiring unit 46, sets at least one of a transmitting phase of a transmitted exciting pulse, a transmitting phase of a refocusing pulse, a shift amount of the relative phase difference between the transmitted exciting phase and the refocusing pulse, and an intensity of a gradient pulse in a readout direction as a capturing condition, and blood flow image capturing units 31, 40, 42, 44 that create blood flow images of the object by performing an imaging scan on the basis of the capturing condition set by the capturing condition setting unit 45.
