A magnetic resonance imaging apparatus includes: an arranging unit that arranges magnetic resonance signals acquired by implementing parallel imaging and correspond to a plurality of channels into a first region on a k-space so as to be positioned at first interval to generate first k-space data and into a second region larger than the first region so as to be positioned at second interval larger than the first interval to generate second k-space data; a generating unit that generates third k-space data at the first interval corresponding to each of the plurality of channels, based on the second k-space data; and a reconstructing unit that reconstructs a magnetic resonance image, based on the first k-space data, the third k-space data, and sensitivity distributions corresponding to the plurality of channels.
