In the current study, the feasibility of random vessel-encoded ASL (rVE-ASL) was evaluated by comparison with the standard vessel-encoded ASL (VE-ASL) in healthy subjects as well as in ischemic stroke patients. Our results showed the perfusion territory maps of rVE-ASL were well matched with those of VE-ASL. The collaterals detected by rVE-ASL were consistent with DSA in stroke patients, suggesting the potential clinical utility of rVE-ASL to characterize collateral circulation in stroke.
