From: A fat suppressed adiabatic T2-preparation module for 3T
Sequence diagram for proposed fat-suppressed adiabatic T2-preparation pulse. This preparation module is composed of three parts: 1) a composite binomial pulse consisting of 3 rectangular pulses with 1:2:1 amplitude ratio for only selecting water spins, 2) four adiabatic refocusing pulses (BIREF-1), and 3) a composite binomial pulse consisting of 3 rectangular pulses with 1:2:7 amplitude ratio to arrange water and fat spins on the +Z and -Z axis, respectively.
