MRI sequence parameters

Listed in the table below are the most common acquisition parameters for commonly used MRI pulse sequences (in msec).

For a general introduction to these sequences please refer to MRI sequences (basic).

The specific parameters for any given study varies from one manufacturer to another, and from one imaging center to another. 

T1

  • TR: <800
  • TE: <30
  • flip angle: 90 degrees

PD

  • TR: >1000
  • TE: <30
  • flip angle: 90 degrees

T2

  • TR: >2000
  • TE: >80
  • flip angle: 90 degrees

FSE T2

  • TR: >2000
  • TE: >60
  • flip angle: 90 degrees

GRE T1

  • TR: variable
  • TE: <30
  • flip angle: 70-110 degrees

GRE T2*

  • TR: variable
  • TE: <30
  • flip angle: 5-20 degrees

STIR

  • TR: >2000
  • TE: >60
  • flip angle: 180 -> 90 degrees
  • inversion time (TI): 120-170

FLAIR

  • TR: >3000
  • TE: >80
  • variable 
  • 1700–2200
