Hi:
I have an MRI of a 34 years old patient that have a brain atrophy,
but with freesurefer I got an ICV of 1120 cc that is near the normal
size for her age... I review the talairach transform, but I think it is
ok... What could be the problem ?... Could I upload the MRI volume ?...
Freesurfer's estimate of ICV (eTIV) is designed to be insensitive to
brain atrophy -- after all, it is an estimate of intracranial volume,
not brain volume. See the Buckner et al. (2004) paper for a validation
of this.
cheers,
