A novel multi-delay multi-parametric pseudo-continuous ASL (pCASL) protocol was presented. Its accuracy was evaluated by comparison with dynamic susceptibility contrast (DSC) enhanced perfusion MRI in 29 patients with acute and subacute ischemic stroke. Consistent results between multiple hemodynamic parameters derived using ASL and DSC were demonstrated.
