The embodiment of the invention discloses a magnetic resonance angiography method, a device and equipment. The method comprises the following steps that: a first imaging sequence is applied to a measured part to obtain a first set of magnetic resonance signals, wherein the measured part comprises blood flow, the first imaging sequence comprises a first inversion recovery radio frequency pulse anda first gradient pulse, and the first gradient pulse is used for inhibiting phase information of the blood flow; a second imaging sequence is applied to the measured part to obtain a second set of magnetic resonance signals, wherein the second imaging sequence comprises a second inversion recovery radio frequency pulse and a second gradient pulse, and the second gradient pulse is used for obtaining phase information of the blood flow; and the blood flow velocity of the measured part is determined according to the first set of magnetic resonance signals and the second set of magnetic resonancesignals. According to the embodiment of the invention, the imaging sequence is improved, so that the problem that magnetic resonance scanning needs to be repeated for multiple times is solved, and themagnetic resonance angiography efficiency is improved.
