Purpose Arterial‐spin‐labeling (ASL) magnetic resonance imaging (MRI) is intrinsically a low signal‐to‐noise ratio (SNR) technique. This study aims to enhance its sensitivity by quantifying physiological noise attributed to cardiac pulsation and devising an improved sequence, cardiac‐triggered ASL,...
