Arterial spin labeling (ASL) imaging is included in the Lifespan Human Connectome Projects (HCPs) in order to investigate the evolution of cerebral blood flow (CBF) in children and elderly populations. To push the limits of ASL imaging for the Lifespan HCPs, we optimized and evaluated high-resolution 2D slice accelerated protocols for multi-delay PCASL imaging. The results suggest that high quality arterial transit time (ATT) and CBF maps with a 2.5 mm resolution can be reliably achieved in about 5.5 minutes.
