Claus,
One approach to do a direct thickness comparison, as was done for a
test-retest study described here:

There's a link on this page to the paper that was published.
That might be all you need. It is also possible to use mri_

that I still know how do do a group comparison (e.g. patients vs
controls).
I have, however, never tried analyses of groups at differen
