While blood bolus dispersion has been shown to affect cerebral ASL, this effect has not yet been adressed for myocardial ASL. In this contribution, we employ computational fluid dynamics simulations in a realistic coronary artery model to evaluate the extent of dispersion in myocardial ASL and its impact on resulting myocardial blood flow values.
