ABSTRACT:
A method for eliminating flow, motion and aliasing artifacts includes a series of saturation pulse sequences which are interleaved with the NMR pulse sequences used to acquire the data needed to reconstruct the desired image. Whereas, the NMR pulse sequences extract data from the volume of interest to be imaged, the saturation pulse sequences excite and saturate spins in the adjacent regions.
