fast spin echo

fast spin echo

a spin echo pulse sequence in which 4-16 echoes are obtained for each excitation, reducing scan time proportionately; each echo is separately phase encoded.

fast spin echo

An MRI term for a fast spin echo pulse sequence characterised by a series of rapidly applied 180° rephasing pulses and multiple echoes, changing the phase encoding gradient for each echo.
