Difficulties with NMR studies of lung arising from low tissue density and air-tissue interfaces can be partially overcome using 13C-DNP NMR. This experiment studies the evolution of the [1-13C] lactate signal in isolated, perfused rat lungs after injection of pyruvate under normoxic and ischemic conditions in order to understand changes in lung oxidative state, central to ischemia-reperfusion injury, transplantation, and metabolic changes in cancer.
