Patent ID: 8483466

Claim:
A magnetic resonance imaging apparatus comprising: a measurement controller that subjects an examinee to a measurement of an echo signal based on application of a positive-polarity flow encode pulse and a measurement of an echo signal based on application of a negative-polarity flow encode pulse, both flow encodes corresponding to a predetermined flow encode, in respective phase encodes; and a calculation processor that reconstructs a blood vessel image of the examinee by using the echo signal based on the application of the positive-polarity flow encode pulse and the echo signal based on the application of the negative-polarity flow encode pulse, characterized in that the measurement controller performs a measurement of plural echo signals having different flow encode absolute values in the respective phase encodes, and the calculation processor reconstructs the blood vessel image by using the plural echo signals having the different flow encode absolute values; and the magnetic resonance imaging apparatus further comprising a blood flow velocity setting unit that accepts an input of a desired blood flow velocity, wherein the calculation processor determines a plurality of the flow encodes in accordance with the input and set blood flow velocity, and the measurement controller measures an echo signal of each of the plural determined flow encodes with respect to each of the plural phase encodes.
