This article contains a list of commonly and less commonly used MRI pulse sequence abbreviations and their meaning. If available, an explanation is included in a separate article.
-
spin echo sequences (SE)
-
T1: T1 weighted
- IR: inversion recovery
- T2 : T2 weighted
-
T2*:
- BOLD imaging: blood oxygen level dependent imaging
- FSE/TSE: fast/turbo spin echo
- TGSE: turbo gradient spin echo
-
3D fast spin echo: isotropic 3D sequences, allowing multiplanar reformats
- 3D MVOX: 3D multivoxel (Canon)
- CUBE (GE): not an abbreviation
- isoFSE (Hitachi)
- SPACE: sampling perfection with application optimized contrasts using different flip angle evolution (Siemens)
- VISTA: 3D volume isotropic turbo spin echo acquisition (Philips)
-
T1: T1 weighted
-
gradient echo sequences (GRE)
- 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, volumetric interpolated brain examination
- CISS: constructive interference in steady-state
- FIESTA: fast imaging employing steady-state acquisition
- MERGE: multipleecho recombined gradient echo
- MEDIC : multi-echo data image combination
- diffusion-weighted (DW) sequences:
- SWI: susceptibility weighted imaging
- inversion recovery (IR) sequences:
-
MR angiography (MRA):
- TOF: time of flight
- MOTSA: multiple overlapping thin slab acquisitions
