Is this for an ROI-based study or a map-based study? For ROI, we use the GTM, and it PV corrects for all structures (including WM and CSF). For map-based, we use MG. MG removes WM (and CSF) entirely. In theory, it can be run in a way to keep WM and throw GM and CSF away, but that is not implemented. Does this answer your questions?

Dear Dr Greeve, I am following petsurfer pipeline to do surface based analysis of PET-FDG data and I have interest in doing partial volume correction. I would like to inquire about:
- Can partial volume correction be applied on white mater, or just on
gray matter?
- Can partial volume correction be applied between gray matter and CSF?
According to Muller-Gartner (MG) Method we segment the brain to gray/white and csf, then we apply partial volume correction only on gray matter. why not on the other parts.
I apologies if my question is basics and I appreciate your input.
Thanks for publishing this valuable manuscript
