A method is provided for improved visualization of vascular structures contained
within magnetic resonance angiograms, particularly steady-state contrast-enhanced
magnetic resonance angiograms. The disclosed methods include manipulating the relative
enhancement levels of the arterial and venous blood pools images with respect to
each other and to the surrounding anatomy. This manipulation is meant to optimize
visualization of one or both of the individual blood pools without the necessity
of completely obscuring or removing the supporting information given by presentation
of the other blood pool and/or the surrounding anatomy.
