We present an improved velocity-selective (VS) labeling pulse for myocardial arterial spin labeling (ASL) that addresses limitations of prior pulses. The proposed pulse is designed using a Fourier Transform based Velocity-Selective (FT-VS) pulse train and optimized to label coronary blood while not labeling myocardium. Myocardial VSASL experiments were performed in healthy adult volunteers. The proposed pulse provided comparable measurements to FAIR ASL and a 2.5-fold reduction in physiological noise compared to a prior VS-ASL pulse.
