MRA at 3T is sensitive to patient motion which sometimes occur due to severe illness. This work investigated the effect of optic prospective motion correction (PMC) on the MRA at 3T. MRA with optic PMC was tested in phantom and on a healthy volunteer and compared with MRA without PMC. The use of PMC successfully reversed the slab misalignment, artifactual stenosis, and discontinuous major arteries caused by the intentional motion by the volunteer, and enhanced the distal vessels. This study demonstrated the potential of optic PMC in improving the quality of MRA on patients with difficulty holding still.
