External Email - Use Caution

Hi Folks,

1) Can I derive a measure of extra-axial CSF. I realize this must be generated in order to create the boundary between the skull and dura but not sure if this is saved in as one of the labels.

2) To generate a measure for Total Cerebral Volume Gray Matter would I combine the following labels? lhCortex + rhCortex + SubCortGray + CerebellumGM

Thank you,

Deana
