hi
matt: could you generate the myelin maps say from two flash scans at different flip angles?
bruce: if one had a choice between an mprage + t2 flair and 2 flash scans at 5/20 flip angles, what would be your recommendation?
cheers,
satra

If you get an MPRAGE and T2-SPACE you can make myelin maps too. FreeSurfer's final surface placement benefits a lot from high resolution images (less than 1mm) and you can still get good SNR with when you use 32-channel coils.
Peace,
Matt.

Yes, definitely. The t2-space flair is a big help

Hi Bruce, So would you recommend acquiring a T2 in addition to an (ME)MPRAGE/SPGR? i.e. is it worth squeezing another acquisition into a protocol?

Hi Warren
yes, it will be part of the upcoming 5.2 release, hopefully in Dec. It will use either a FLAIR or T2 (ideally T2-SPACE for either one)

Hi all,
Back in January and October Bruce mentioned that he had under development some scripts designed to utilize T2-SPACE images for better pial surface reconstruction in the presence of dura -- I was just wondering if any of that is ready for trial?
Thanks!
Warren
