A magnetic resonance imaging capable of decreasing ghost-like artifacts peculiar to a fast SE method etc. so that an image exhibiting high image quality is obtained. A magnetic resonance imaging apparatus, as one aspect, having an arrangement that one exciting pulse (90 DEG ) is supplied to a subject of an inspection placed in a static magnetic field so that a desired sliced plane is excited and then a plurality of refocusing pulses (180 DEG ) are sequentially supplied to the sliced plane so that an image is reconstructed in response to a plurality of spin echo signals (R1, R2, R3, R4) generated due to energization caused by the plurality of refocusing pulses. The magnetic resonance imaging apparatus further includes an acquisition order changing unit for changing the order of levels of phase encoding, to which the plurality of spin echo signals are subjected, at each radio frequency excitation using the exciting pulse, a receiving unit for receiving the spin echo signals on which the phase encoding gradient pulses (GE) of the changed levels in accordance with the acquisition order are applied, and a data arranging unit for arranging the echo data in the Fourier space correspondingly to the acquisition order. <IMAGE> |
