Abstract
Functional Magnetic Resonance Imaging (fMRI) would benefit much from high-quality MR, Angiography (MRA) of the vascular system underlying the functional domain. Ideally fMRI and MRA are performed during the same experiment. Unfortunately, conventional MRA leads to a systematic underestimation of vessels and images with a generally low contrast. Therefore, we developed a method that combines MRA images from 3 different spatial directions, thus circumventing the most prominent MRA problems. Our method delivers a geometric 3D model of the vessel system that allows visualizations and quantifications beyond the scope of the typically used maximum intensity projections.
