Abstract
Blood pool contrast agents for Magnetic Resonance Angiography (MRA) have a prolonged intravascular half-life and therefore have the potential for visualizing large anatomical regions with high resolution. A potential problem is that both the arteries and veins are enhanced, resulting in venous overprojection in Maximum Intensity Projections (MIPs), which are most widely used for inspecting MRA datasets. In this paper a novel approach for improved arterial visualization is introduced. It is based on suppressing the major overlapping veins in MIPs. The approach is illustrated on MRA images of the peripheral vasculature acquired using the blood pool agent NC100150. The resulting visualizations are compared to Digital Subtraction Angiography (DSA) images.
