Mapping metabolic rate constants is of high physiological relevance, as for instance the metabolic activity is increased in tumours. In this work, spectral-spatial excitation is used to selectively excite, image and crush the downstream metabolites lactate and alanine. A small tip angle selective imaging of the injected [1-13C]pyruvate then gives the necessary reference for turnover images.
