Hi Greg,
yes, that can happen where they are hyper-intense on T2 and hypo-intense on
T1 and thus look like GM on the T1. It's not that common since they are
usually deeper, but we have seen it.
sorry

a collaborator just got a grant review that claimedÂ
There's a possibility that changes in cortical thickness in
the insula might be a consequence of lesions (MR-hyperintensities) in the white

i would think that white matter hyper intensities would tend to enhance
freesurfers ability
to detect the white matter/grey matter boundary rather than cause an error.
any comments as to the correctness of my thinking would be appreciated.
thank you
greg
