This study aimed to apply compressed sensing in 2D proton MRSI. Both phantom and in vivo rodent brain MRSI experiments were performed on a 7T Bruker scanner with compressed sensing reconstruction. Results showed that the proposed method could yield high resolution MRSI without loss of spectral accuracy with a large understanding factor (30%).
