And I would say if you want to do T1w/T2w myelin mapping the T2w scan will give you more contrast for that, as the fluid inversion does seem to reduce your contrast for myelin some (though it may increase your contrast for CSF). FLAIR can be useful for other things (like seeing some kinds of

Hello, I am beginning a new study and would like to determine the optimal T2 acquisition parameters for improved pial surface results from FreeSurfer. I am wondering if there is a difference in using a T2 or T2-FLAIR. I have found a discussion post from 2014 which provided useful information
