Using a Parahydrogen-induced polarization (PHIP) based approach, we enhanced the signal of pyruvate, one of the key metabolites for energy production in the body. By injecting this metabolite into a mouse carrying a human melanoma tumor, we could perform real time spectroscopy and visualization of the tumors metabolism using a NMR machine. This offers a fast and powerful tool for metabolic imaging without using radio tracers.
