Purpose To further develop MultiNet GRAPPA, a neural‐network‐based reconstruction, for lower SNR proton MRSI (1H MRSI) data using adapted undersampling schemes and improved training sets. Methods 1H FID‐MRSI data and an anatomical image for GRAPPA reconstruction were acquired in two slices in the hu...
