Bloch simulation of Mzss.

Bloch simulation of longitudinal steady state magnetization (Mzss) temporal variation in one repetition time (TR) at different flip angle (FA) (unit: degree). Mzss achieved steady state much more quickly as FA increased. Short recovery of longitudinal magnetization during water suppression was compensated for in Eq 1. RD: recovery delay between PRESS and the interleaved RF and gradient pulses (iPFG) train.
