Dear,

 

I do have some questions linked to RBV PVC implemented in Freesurfer:

1. Could you please tell me how the RBV PVC is acquired? Is the RBV PVC acquired based on Muller-Gartner (on a region-level, and based on only using gray- versus white matter), or when and how are the different regions from gtm_seg applied to obtain GTM?
2. What would be the advantage of using your technique compared to for instance sGTM?
3. Could you please tell me the difference in region-definition between aparc+aseg and the gtm_seg? (I saw that the latter contains less regions compared to aparc+aseg.) What is the reason to use the latter compared to the aparc+aseg, based on the definitions of the regions? (I know that gtm_seg is used which has a high resolution, but not quite sure, apart from the resolution, why you are not using aparc+aseg for the RBV PVC.)
4. Is there a mask applied to the gtm_seg to exclude regions that are located outside the brain?

 

Many thanks for your answers.

Kind regards,

Nathalie
