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.
