Magnetic resonance angiography (MRA) sequences generate an amount of data that represents the signal intensity of voxels from the image volume, distributed on consecutive slices and oriented on a user-defined plane. In particular, the availability of wide anatomic coverage coils and high-field scanners, together with fast sequences and high relaxivity contrast media, allows to easily obtain MRA series formed by a high number of thin slices, usually partially overlapped on each other. This poses the problem to achieve a synthetic view of such a large quantity of analytical information, as derived from each single partition, through either a panoramic or a targeted visualization of a given vascular territory. The demonstration of a particular vascular anatomy may also raise the issue of separating or eliminating other structures contained in the same image volume (such as veins in an MR arteriogram, superimposed vessels or stationary tissues with contrast enhancement).
