<p><P>PROBLEM TO BE SOLVED: To reduce the imaging time and to generate the blood flow image where the signal intensity in the stationary tissue is erased with high accuracy. <P>SOLUTION: An MRI apparatus includes a data collection unit, an image reconstruction unit, a reference image generation unit, and a fluid image generation unit. The data collection unit repetitively performs a tag mode of applying an RF wave to at least an upstream portion of an imaging area to perform fluid labeling of a fluid flown into the imaging area and, after a lapse of an inversion time from application of the RF wave, performing magnetic resonance data collection, while changing the inversion time. The image reconstruction unit reconstructs a plurality of tag images corresponding to a plurality of different inversion times based on the magnetic resonance data collected in the tag mode. The reference image generation unit generates a reference image based on the plurality of the tag images. The fluid image generation unit generates a subtraction image between each of the tag images and the reference image as a fluid image. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
