The eTIV we report is not based on counting voxels inside the skull.
Instead, it is based on a statistical relationship between the TIV
computed from a manual segmentation and the talairach transfrom (see
Randy Buckner's paper). I don't know whether the original manual segs
included CSF (I assume it did).

Hello,
I have a question about the eTIV intracranial volume calculation.
My question is:
Does the eTIV intracranial volume include everything interior to the
outer pial surface
(excluding the skull, eyes, neck and dura), and does it also include
the CSF?
That's all.
Thank you for your time.
