3D angiography with pseudo continuous Arterial Spin Labeling (PCASL) tagging scheme and accelerated radial sampling pattern has been implemented. Feasibility studies on intracranial vasculature have been done on healthy volunteer and images show large coverage, transparent background, isotropic resolution, high contrast and SNR. Comparison with standard 3D TOF demonstrate the advantage of 3D PCASL angiography on substantially improved visualization of vessels with slow filling.
