A magnetic resonance imaging apparatus comprises an imaging condition setting unit, a receiving unit, an image reconstructing unit, an image distortion correcting unit and an image correction estimating unit. The imaging condition setting unit sets mutually different image conditions. The receiving unit receives magnetic resonance signals from an imaging area according to the image conditions. The image reconstructing unit reconstructs a plurality of image data corresponding to the image conditions respectively based on the magnetic resonance signals. The image distortion correcting unit corrects distortions of the plurality of the image data based on a magnetic field distribution on the imaging area. The image correction estimating unit estimates whether a correction of at least one of the plurality of the image data is appropriate based on a plurality of corrected image data.
