actually Matt Glasser points out that a brief description is in his paper
that is coming out soon, and there is also some description in Andre's
multi-echo mprage paper

Hi Bruce,
Out of curiosity and for reference for my users, do you have a paper on the T2
or FLAIR assisted segmentation?
Cheers,

Hi Katie
I'm really not sure. These days I would recommend a highres (e.g. 1mm
isotropic) FLAIR if you can get one, or T2 if not. The T2* can help, but
it's pretty noisy in brain.
cheers

Dear Freesurfer gurus,
At the course, André van der Kouwe mentioned in his morphometry methods talk
that T2* weighted contrast from
MEMPRAGE could be used to further seperate dura from cortex, as also discussed
in this paper:
http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2408694/. We have a GE scanner in
our lab. The internet suggests
that a Multi-echo FSPGR/FGRE exists. Would this be the analog? Would it work
the same way? Could you also
use these images with the mris_make_surfaces command?
Thanks very much for your insight -- and I enjoyed the course!
