Metabolic imaging of hyperpolarised [1-3C]pyruvate and its downstream metabolites requires efficient encoding methods. Parallel imaging is widely applied to 1H MRI, but not yet to hyperpolarised MRI. In this work, IDEAL spiral CSI was combined with parallel imaging and advanced reconstruction methods. CG SENSE and SPIRiT were compared to gridding reconstruction and regular SENSE unfolding. Results in kidney show high quality dynamic data with improved SNR for SPIRiT and CG SENSE.
