## Abstract A new method for the simultaneous suppression of water and lipid resonances using a series of dualβband frequencyβselective radiofrequency (RF) pulses with associated dephasing gradients is presented. By optimizing the nutation angles of the individual pulses, the water and lipid suppre
was evaluated for in vivo brain proton surface coil NMR spectroscopy. The studies were performed on cat brain using surface coils at 4.7 T. The sequence produced brain spectra with adequate water suppression, and a broader excitation profile than sequences which form spin echoes using 133 1 pulses (
