steady-state free precession

steady-state free precession

An MRI term for any field echo or gradient echo sequence in which a non-zero steady state develops for both transverse and longitudinal components of magnetisation. If the radio frequency pulses are close enough the MR signal never completely decays, meaning that spins in the transverse (x-z) plane never completely dephase.
