In parallel transmit, phase-relaxed RF pulse design significantly improves image quality in gradient echo and spin echo images. Here we present a simulation study showing that phase-relaxed 90-180 RF pulses can also be used in fast spin echo imaging with Le Rouxs quadratic phase modulation implemented on all transmit channels.
