# Measure Mask, MaskVol, Mask Volume, 1378561.000000, mm^3 # Measure BrainSeg, BrainSegVol, Brain Segmentation Volume, 1112716.172377, mm^3 # Measure BrainSegNotVent, BrainSegVolNotVent, Brain Segmentation Volume Without Ventricles, 1095647.392151, mm^3 # Measure SupraTentorial, SupraTentorialVol, Supratentorial volume, 966887.205081, mm^3 # Measure SupraTentorialNotVent, SupraTentorialVolNotVent, Supratentorial volume, 949818.424855, mm^3 # Measure SubCortGray, SubCortGrayVol, Subcortical gray matter volume, 58370.262413, mm^3 # Measure rhCerebralWhiteMatter, rhCerebralWhiteMatterVol, Right hemisphere cerebral white matter volume, 235981.558256, mm^3 # Measure lhCerebralWhiteMatter, lhCerebralWhiteMatterVol, Left hemisphere cerebral white matter volume, 231717.193880, mm^3 # Measure CerebralWhiteMatter, CerebralWhiteMatterVol, Total cerebral white matter volume, 467698.752136, mm^3
I don’t see any eTIV.
