Hyperpolarized metabolic imaging of the heart suffers from limited spatial specificity in current protocols. In this work two algorithms, k-t PCA and k-t SPARSE, that allow accelerated metabolic imaging are compared in simulations and used to acquire in-vivo metabolic maps in rats at one millimeter in-plane resolution.
