Hi Peter, recon-all produces an estimate of ICV. In aseg.stats there is a line that looks like:
# Measure EstimatedTotalIntraCranialVol, eTIV, Estimated Total Intracranial Volume, 1696008.240403, mm^3 You can read more about how it is computed at https://surfer.nmr.mgh.harvard.edu/fswiki/eTIV -Paul ________________________________________ From: freesurfer-boun...@nmr.mgh.harvard.edu <freesurfer-boun...@nmr.mgh.harvard.edu> on behalf of Mirsol Choi <mir...@ualberta.ca> Sent: Wednesday, November 1, 2023 5:23 PM To: Freesurfer support list Subject: [Freesurfer] Finding Intracranial volume External Email - Use Caution Hi fellow freesurfers! I am a Masters student currently working with diffusion images. I would like to ask you experts how I can obtain ICV from my T1/T2 or diffusion images. Is there a certain output from recon-all that produces intracranial volume? Or is there a different command I must use? Thank you all so much for your time. I look forward to hearing from you.
