Schematic diagram demonstrating the fate of infused 13C labelled acetate upon incorporation into hepatic metabolism. Following degradation to 13C Acetyl CoA, fractional enrichment of hepatic 13C glutamate (with the 13C nucleus at the C5 position) is measurable on the MR visible spectrum, enabling calculation of TCA cycle flux.
