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://secure-web.cisco.com/1jljg6dkUgcWIVn7pjegiZm1C7K-LPzZxj3WP5JbiWaMqmb...

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.

Peter
