We demonstrate the design of adiabatic multi-band inversion pulses with high time-bandwidth products and acceptable RF power demands. The proposed utilization of GOIA single-band pulses results in smooth slice selective gradients with highly reduced RF power and matched multi-band RF waveforms. Phantom and in vivo experiments at 3T and 7T validate the simulations and demonstrate robust inversion of multiple slices over a wide range of both B1+ and B0 values.
