The overdiscrete reconstruction, originally proposed for 1H MR Spectroscopic Imaging (MRSI), is adapted and applied to hyperpolarized 13C MRSI. The method is demonstrated for in-vivo hyperpolarized [1-13C]-pyruvate scans of a pig’s kidneys using phase encoded 2D-MRS. Linewidth and spectral separation were improved in addition to a significant signal enhancement for low concentrated downstream metabolites such as lactate, alanine and pyruvate-hydrate.
