A magnetic resonance imaging apparatus that can display an image showing conditions of tissues such as water and fat more accurately is provided. For this purpose, the signal processing unit 110 processes signals of each pixel of the first image 506 generated based on an NMR signal for each pixel of the first image 506 in order to generate the second image 509 and determines an order of processing unprocessed pixels of the first image 506 by preferentially selecting the unprocessed pixels with a high signal strength from among a plurality of unprocessed pixels for which no process has not been performed yet that are adjacent to the already-processed pixels of the first image 506.
