"Saturation recovery sequences consist of multiple 90 degree RF pulses at relatively short repetition times (TR) 1. An example of a SR sequence is shown below. Residual longitudinal magnetisation after the first 90 degree RF pulse is dephased by a spoiling gradient (in this case with the slice select gradient). Longitudinal magnetisation that develops during the TR period after the dephasing gradient is rotated into the transverse plane by another 90 degree pulse. A gradient echo is acquired immediately after this. The signal will reflect T1 differences in tissues because of different amounts of longitudinal recovery during the TR period."
