Abstract
A perfusion image is produced by acquiring a series of time course MR images from an imaging slice. During the acquisition spins flowing into the slice are repeatedly tagged with an RF tagging pulse having a flip angle that is modulated according to a tagging pattern. Voxels in the series of reconstructed MR images having signals which vary according to the tagging pattern indicate perfusion. Perfusion images indicating either flow or velocity are produced.
