Abstract
MRA data is acquired from a large, longitudinal region of interest by translating the patient through the more limited longitudinal FOV of the MRI system as a three-dimensional MRA data set are acquired. Patient table movement is controlled to track a bolus of contrast agent as it passes through the region of interest. A seamless image of the entire region of interest is reconstructed after correcting the phase of acquired MRA data to reduce the signal falloff at abutting longitudinal FOVs. Phase corrections are determined from the central DC views acquired during the scan.
