Hi all,
I'm building a scan protocol for what
is primarily a MEG study, which needs T1 information for co-registration
and T1/T2 information to construct an accurate BEM from the inner skull
surface. It seems like the two multi-echo FLASH sequences at 5 and 30
degrees would give me all of the information that I need without an
MPRAGE, but I'm not sure how well the two MEFs work in the standard
Freesurfer pipeline.
Would it be reasonable to acquire no MPRAGE but two
MEF sequences at 5 and 30 degrees, combine them following the
method from
https://surfer.nmr.mgh.harvard.edu/fswiki/MEF, and send the resulting T1 to recon-all? With my scan time constraints,
the alternative would be to acquire a multi-echo MPRAGE and a single
5-degree MEF.
Thanks for any help on what is probably a naïve question.
