PROBLEM TO BE SOLVED: To emphasize a fluid which flows at a comparatively lower speed than a fluid which flows at a higher speed. SOLUTION: A collecting means including a sequencer 10 and parts and the like controlled by the sequencer 10 collects magnetic resonance signals which are generated in a photographing region before an administration of a contrast agent by making the magnetic resonance signals be dephased in such a manner that magnetic resonance signals for the fluid which flows in a first flow-rate range makes greater signal reducion than those for the fluid which flows in a second flow rate range of a lower flow rate. At the same time, the collecting means collects the magnetic resonance signals which are generated in the photographing region after the administration of the contrast agent in a manner to make the magnetic resonance signals have an intensity in response to the concentration of the contrast agent. An operation unit 11 respectively reconstructs base images and dynamic images indicating spacial distribution of the fluids in the photographing region on the basis of the magnetic resonance signals respectively collected by reflecting the intensity of the magnetic resonance signals, and forms images for diagnosis indicating the degree of the changs of the fluids after the administration of the contrast agent with respect to the fluid before the administration of the contrast agent based on those images.
