We developed a fast volumetric chemical shift imaging sequence for imaging of hyperpolarized [2-13C]Pyruvate and its products, without suffering chemical shift displacement artifact due to the large spectral dispersion of [2-13C]Pyruvate and its products, and applied it to measuring brain metabolism in healthy and C6 glioma-bearing rats.
