Hi Team,
Could you please confirm whether the below mentioned formulas to compute Total WM and ventricular CSF are correct
1. Total White Matter = CerebralWhiteMatterVol + (lh+rh) Cerebellum White Matter
2. Total ventricular CSF = (lh + rh) Lateral-Ventricle + = (lh + rh)Inf-Lat-Vent + (lh + rh)choroid-plexus + 3rd-Ventricle + 4th-Ventricle
Thanks for your support.
Regards, Janani

looks right, though some times people will include brainstem as part of WM
2.Total ventricular CSF = (lh + rh) Lateral-Ventricle + = (lh + rh)Inf-Lat-Vent + (lh + rh)choroid-plexus + 3rd-Ventricle + 4th-Ventricle
There is a 5th ventricle (which I think is basically the aqueduct). There is also a segment called "CSF" (24) but can't remember what gets labeled as "CSF"
Thanks for your support.
