Objective Improving the readout for arterial spin labeling with multiple post-labeling delays (multi-PLD ASL) through a flip angle (FA) sweep towards increasing contrast-to-noise ratio for long PLD images. Methods Images were acquired from 20 healthy subjects and 14 patients with severe, asymptomati...
