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.
