According to one embodiment, a magnetic resonance imaging apparatus includes a data collection unit which collects magnetic resonance data from a patient by a half Fourier method using a plurality of coils an unfolding unit which performs an unfolding process on a plurality of items of folded image data obtained from the plurality of coils to generate unfolded image data by using sensitivity data of the plurality of coils and a data processing unit which repeatedly performs a data filling process and a phase correction process to improve accuracy of data in an unsampled region to generate image data for display, the data filling process filling the unsampled region in k-space with k-space data obtained by Fourier-transforming the unfolded image data and the unsampled region being a region for which the data have not been collected.
