The feasibility of accelerating arterial spin labelling (ASL) by exploiting spatiotemporal correlations for assessing myocardial perfusion in small animals is demonstrated. Based on numerical simulations and retrospectively undersampled in-vivo data, three-fold acceleration yields errors below 16 ± 10 % in myocardial blood flow quantification and hence the method is considered promising to shorten the long scan times of myocardial ASL in small animals.
