A system for fat signal suppression in MR imaging comprises an RF signal generator for generating RF pulses in an MR pulse sequence using one or more RF pulses for echo signal formation including, an RF excitation pulse and an RF refocusing pulse subsequent to said RF excitation pulse. A magnetic field slice select gradient generator generates first and second different slice select magnetic field gradients for corresponding use with the RF excitation pulse and the RF refocusing pulse, respectively, the first and second different slice select magnetic field gradients having substantially different amplitudes. An MR imaging control unit directs acquisition of MR imaging data having fat signal substantially suppressed using the generated RF pulses and different slice select magnetic field gradients.
