The influence of atherosclerotic plaques on bolus
dispersion in contrast-enhanced myocardial perfusion
imaging has not yet been studied in detail. In this
contribution, we use computational fluid dynamics
simulations in a high-detailed coronary vascular model
to study the impact of both stenosis grade and
morphology on bolus dispersion and, consequently, on MBF
quantification.
