(MEMP) Sequence with a multislice and multi echo acquisition in one TR.

(MSE) A spin echo technique with a flip angle over 90°.

See Spin Echo Sequence and Fast Spin Echo.

(PSIF) A heavily T2* weighted contrast enhanced gradient echo (mirrored FISP) technique. Because TE is relatively long, there are much flow artifacts and less signal to noise. In normal gradient echo techniques a FID-signal results after the RF pulses. This FID is rephased very fast and just before the next FID follows a spin echo signal. The SE is spoiled in FLASH sequences, but with PSIF sequences, only the SE is measured, not the FID.
