Abstract
MRA data is acquired from a large region of interest by translating the patient to successive stations at which successive portions of the three-dimensional MRA data set are acquired. Patient movement is chosen to track a bolus of contrast agent as it passes through the region of interest and a 3D acquisition is performed at a succession of stations. The order and shape in which k-space is sampled differs from station-to-station to achieve maximum image contrast.
