Fig. 1.
A 180° inversion pulse is followed by a train of turbo field-echo readouts. α=flip angle (FA), TE=echo time, TR=repetition time, TI=inversion time, TFE=turbo field-echo factor (number of α-pulses), TD=delay time and TS=shot interval. The cross-hatched boxes represent acquisition. Centric k-space encoding is used.
