(TurboFLASH) This FLASH-based sequence use an inversion pulse followed by a low flip angle and short TR gradient echo train. This gradient echo technique forms complete images in times short compared to T1. Images obtained in this way have very little intrinsic contrast, maintaining adequate signal requires that losses (and therefore contrast).

(TurboGRASS) This GRASS-based sequence use an inversion pulse followed by a low flip angle and short TR gradient echo train.
