Non-contrast 3D TOF MR angiography has been widely accepted as a clinic tool for evaluation of intracranial arteries. Multiple slabs are usually desired to cover a large field of view in the z direction, which induces long scan time. We hypothesize that it is feasible to combine 2D partial Fourier and sensitivity encoding with 3D TOF MRA providing reduced scan time and high diagnostic image quality. Phantom and volunteer experiments were performed to test the hypothesis.
