Four dimensional (4D) MR Angiography based on Pseudo-Continuous Arterial Spin Labeling (pCASL) combined with CENTRA-Keyhole and View-sharing (4D-PACK) was accelerated for whole brain 4D-MRA. Compressed-Sensing combined with Sensitivity Encoding (Compressed-SENSE) was used and we demonstrated whole brain 4D-PACK accelerated with Compressed-SENSE. It provides comparable peripheral and posterior cerebral artery visualizations compared with conventional 4D-PACK which has limited anatomical coverage. Validity of whole brain 4D-MRA is suggested using Compressed-SENSE combined 4D-PACK.
