Vastly undersampled Isotropic Projection Reconstruction (VIPR) [1] techniques have been successfully utilized for time-resolved contrast-enhanced MR angiography (CE-MRA) studies. In this work, we explore the benefits of using the VIPR k-space sampling trajectory, in combination with the HYPR LR processing method, for obtaining high spatial and temporal resolution CE-MRA images of the lower extremities.
