A magnetic resonance imaging apparatus includes a cine-imaging unit, a characterizing-part detecting unit, a motion-analyzing unit, and an image-extracting unit. First, the cine-imaging unit collects the time-series images of a region of interest in a subject and reconstructs an image. Next, the characterizing-part detecting unit detects the characteristics of the time-series images. The motion-analyzing unit analyzes motion-characteristic values of the characteristics extracted by the characterizing-part detecting unit. The image-extracting unit extracts a specified time-series image in accordance with the motion-characteristic values.
