A magnetic resonance imaging apparatus includes a generation unit configured to generate a magnetic field, a reconstruction unit configured to reconstruct an image for a subject on the basis of a magnetic resonance signal radiated from the subject in the magnetic field, a presumption unit configured to presume a distribution of an image quality deterioration degree occurring in the image on the basis of a precision at which the generation unit generates the magnetic field, and a creation unit configured to create a display image showing the distribution of the image quality deterioration degree on the image.
