Using hyperpolarized 13C magnetic resonance imaging (MRI), Timm et al. show that a change in oxidative mitochondrial carbohydrate metabolism precedes cardiac decline in a rat model of heart failure induced by doxorubicin (DOX), a widely used chemotherapeutic agent. This study suggests the possibility of using hyperpolarized MRI to test cancer patients receiving DOX for early signs of cardiotoxicity.
