PROBLEM TO BE SOLVED: To selectively give an effect of an RF prepulse to every echo (that is, every image) and acquire images obtained from the respective echoes with different contrasts in a multiecho measurement in an MRI apparatus.SOLUTION: In an MRI apparatus, when measuring a plurality of echoes from a subject by using a pulse sequence in which an RF prepulse and a multiecho sequence are combined, and reconstructing a plurality of images corresponding to the plurality of echoes respectively, a plurality of k spatial data areas corresponding to each of the plurality of echoes are secured, the plurality of k spatial data areas are respectively divided into a plurality of divided areas, an encode order is determined to differ measurement orders in the divided areas between the plurality of k spatial data areas, and in measuring echo data filling at least some of the divided areas, the pulse sequence is set to execute an RF prepulse part, thereby reconstructing a plurality of images with different RF prepulse effects. |
