Particularly important are the inversion time (TI) in inversion recovery, and the time between 90 Â° pulse and the subsequent 180 Â° pulse to produce a spin echo, which will be approximately one half the spin echo time (TE) . The time between repetitions of pulse sequences is the repetition time (TR) .
