This study aims to investigate the ideal labeling and delay parameters for single-delay, multi-delay and time-encoded pCASL and compare their theoretical performance in cerebral blood flow (CBF) and bolus arrival time (BAT) estimation under realistic noise levels over two BAT ranges: healthy (500ms-1500ms) and disease (500ms-3000ms).
