摘要： 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.
