Single-shot, 3D spiral ASL is incensitive to motion and
susceptibility artifacts and high temporal SNR and
temporal resolution. However, the prolonged read-out
time due to 3D acquisition reduces SNR because of T2
relaxation. In this work we present a 2D in-plane
accelerated acquisition scheme using non-Cartesian
parallel imaging that helps reduce the read-out time and
remain image quality similar to multi-shot acquisitions.
