A new scheme for non-contrast enhanced intracranial three-dimensional dynamic magnetic resonance angiography (4D-MRA) using pseudo-continuous arterial spin labeling (4D-PCASL) is proposed for visualizing inflow and outflow dynamics. The 4D-PCASL procedure was accelerated with contrast-enhanced timing-robust angiography (CENTRA)-Keyhole and the view-sharing techniques (4D-PACK). Images acquired from four volunteers were compared between the 4D-PCASL and 4D-PACK approaches. We show that this new scheme accelerates data acquisition and provides dynamic inflow and outflow information.
