<p>An inverted vertical magnetization generating step (101) in which an inversion RF pulse is applied to a subject to generate inverted magnetization, and a plurality of signal acquiring steps (103-106) are continuously performed. Similar steps are repeated while the inverted vertical magnetization generating step is performed in a slice non-selection mode. A perfusion image is obtained from the difference between the image data acquired at the first signal acquiring steps (103-106) and the image data acquired in the next signal acquiring steps (107-110). Gradient magnetic fields differing at the signal acquiring steps are applied to obtain images with a plurality of slices. By repeating the steps while the correspondence relations between inversion times TI and the selected slices are changed, images whose inversion times are different can be obtained for a plurality of slices in a short time. Thus, images which reflect the hourly variation of perfusion and have a high diagnostic value can be obtained over a wide range.</p> |
