STIR-TR
Is there a rule regarding what the TR should be for a STIR sequence? If so, is the 'rule' different for 1.5 and 3.0 Tesla?

thnx

 My understanding with Stir is to have longer TR and shorter TE than a normal T2 sequence. Ive also wondered this question and have not found a definite answer as I guess it could vary from manufacturer to manufacturer?

Im on a Siemens Avanto 1.5T, and typically our STIR sequence ranges from:

TR = 4000 - 10,000ms (I try not to go beyond 7,000)
TE = 20 - 40ms

...obviously you can adjust values for different outcomes depending what you are trying to identify.
