Multi-channel receive coils can improve coverage for metabolic imaging with hyperpolarised 13C compounds. Combining different receive channels in an SNR-optimal way is challenging due to the difficulties in determining sensitivity maps. The main aim of this work was to implement and optimise a Singular-Value-Decomposition (SVD) based sensitivity map extraction from metabolic images with a single spectral point per metabolite and to investigate its performance in SNR-limited metabolic imaging experiments.
