Hello FreeSurfer Experts,
Is it possible to estimate the sulcal CSF volume in Freesurfer processing?
If not directly are there any indirect means that can give me an estimate?
Thank you

No, not currently. This is quite a hard problem even if you have a T2.
The pulse sequences are usually low enough bandwidth that fat from the
scalp and skull marrow shift into the CSF spaces making it impossible to
properly segment that area as CSF. If you wanted an approximate value,
you coul
Thanks Doug.
I was looking at a paper "ARANGO, C., MCMAHON, R. P., LEFKOWITZ, D. M.,
PEARLSON, G., KIRKPATRICK, B. & BUCHANAN, R. W. 2008. Patterns of cranial,
brain and sulcal CSF volumes in male and female deficit and nondeficit
patients with schizophrenia. Psychiatry Research: Neuroimaging, 16
In theory that works, but remember the FS total cranial volume is only
an estimate based on the talairach transform. It is not counting voxels
that are inside the skull.
