ABSTRACT:
A flow differentiation scheme is disclosed for magnetic resonance imaging (MRI) of fluid flow in regions of turbulent flow. The flow differentiation scheme comprises the steps of (1) obtaining a first magnetic resonance (MR) image of the region, (2) obtaining a second MR image of the same region with an imaging parameter or imaging sequence altered, and (3) logically differentiating the first and second images with respect to flow to create a difference image. The process may be enhanced by superimposing one of the original images, upon an image that has been flow differentiated. As a result, a substantial amount of the static signal is suppressed producing superior angiograms of diseased and undiseased blood vessels. Additionally, the scheme can be used to image any fluid flow in any body or thing.
