Dear all,
i have problems with the interpretation of the sienax results (brain volume). I execute the command with the following options: sienax imagename -B "-R -S -B" -r
I get the following results:
tissue volume unnormalised-volume
pgrey 523846.13 311996.37 (peripheral grey)
vcsf 107070.20 63769.71 (ventricular CSF)
GREY 666438.50 396922.65
WHITE 910137.07 542066.54
BRAIN 1576575.57 938989.19
The brain volume is in this case only the volume of GREY and WHITE. Is the pgrey volume a part of the GREY volume? I want to calculate the total ICV. Do I sum up the four tissue types? Sum up only BRAIN (GREY and WHITE) volume and vcsf volume?
Best regards,
Iven Fellhauer
