[MINC-users] Intracranial Volume

[Dr. Sridar Narayanan]

Hi Jim,

Speak to Louis. He has the code to compute intracranial capacity (ICC) as
part of his BICCR (Brain to ICC Ratio) measure of normalized brain volume.
If you have a PD-weighted scan as part of your acquisition, you should be in
business.
