ABSTRACT:
A T2preparation sequence uses a segmented BIR-4 adiabatic pulse with two substantially equal delays and is insensitive to B1field variations and can simultaneously suppress fat signals with low specific absorption rate (SAR). An adiabatic reverse half passage pulse is applied followed by a predetermined delay. An adiabatic full passage pulse is applied followed by a substantially equal delay, followed by an adiabatic half passage pulse. Fat signal suppression is achieved by increasing or decreasing either the first delay or the second delay.
