Gradient echo MRI sequences

GRE : gradient echo sequences

• SSFP : steady state free precession
• TRUFI : true fast imaging with steady state free precession
• true FISP : fast imaging with steady state free precession
• PSIF : reverse FISP
• DESS : dual echo steady state
• FLASH : fast low angle shot 
• GRASS : gradient recalled acquisition in the steady state
• SPGR : spoiled gradient recalled
• VIBE : volumetric interpolated breath hold examination
