Arterial spin labeled CMR is a non-contrast myocardial perfusion imaging technique capable of assessing coronary artery disease. A limitation of current methods is potential underestimation of blood flow to myocardial segments that have coronary arterial transit time longer than 1 R-R, which are found in regions with significant collateral development from chronic myocardial ischemia. In this work, we demonstrate the feasibility of a velocity selective labeling scheme for ASL-CMR that is insensitive to arterial transit time.
