PROBLEM TO BE SOLVED: To obtain a uniform brightness multi-slice perfusion image by repeating imaging more than one time while changing the order of scan for more than one slice and adding more than one image formed to each of the same slices. SOLUTION: In the first imaging, after a tag T to T1, data collection is made in the order of slices a to e by echo planar imaging(EPI), and then after a control C to T1, data collection is made by the EPI in the same order. In the second imaging, after a tag T to T1, data collection is carried out by the EPI in the order of slices b, c, d, e, a. Subsequently, likewise scan is made for each slice while changing the order of the EPI. Then, a perfusion image concerning the slice a, differential images between tag images and control images are added. The same is repeated similarly for the slices b, c, d, e.
