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

interestingly, in this case i think there may even be reason why white matter
hyper intensities could be
more common in our insular region of interest where we detected thinning. The
disease is HIV and
activated monocytes invade the perivascular spaces where they can cause
inflamation, which
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
matter.
i would think that white matter hyper intensities would tend to enhance
