Fast spin echo sequence

Fast spin echo imaging involves a refinement of the basic spin echo sequence. Instead of eliciting a single signal echo after a 180° rephasing pulse in each cycle of length TR, fast spin echo imaging elicits several signals, an echo-train, by multiple 180° pulses after a single 90° pulse. Earlier echoes (TE < 20 ms) are used to form a proton-density-weighted image and those arriving later (TE > 80 ms) are used to form a T2-weighted image. This pair of dual-echo images provides complementary tissue contrast for no increase in scan time, making fast spin echo a favoured sequence.
