The aim of this study was to use hyperpolarized 13C labeled ketone bodies to examine metabolism in vivo. Despite high polarization (~25%) and long T1 values (~35s), little in vivo metabolism was observed in our current models. Nevertheless, we hope these molecules may still have important roles to play in our understanding of mitochondrial redox state in vivo.
