Through the present invention, BSI data are acquired during open time (in which an RF pulse or gradient magnetic field is not applied) of an ASL image acquisition sequence, in order to acquire a hemodynamic image of blood flowing in and a hemodynamic image of blood flowing out of the same region, or other information of the region, in a short time and without positional misalignment. At this time, BSI data acquired in open time at the time of acquisition of a control image in an ASL image acquisition sequence are disposed in a region of lower spatial frequency in k space than BSI data acquired in open time at the time of acquisition of a label image, and, in open time when each image is acquired, the BSI data are disposed in the region of low spatial frequency in k space to the degree that the data are acquired at a timing at which the effect of a pre-pulse is small.
