Dear Dr Greeve, I interestingly read the manuscript "Different partial volume correction methods lead to different conclusions: An (18)F-FDG-PET study of aging" Thank you for publishing this data.
I understood from this paper that he recommended stream for PVC is to correct the PET images using Muller-Gartner method then feed the corrected maps into three group level analyses: surface based for left and right hemispheres then for subcortical regions..
My question is about the subcortical analysis: To describe this analysis, is it a volumetric analysis for subcortical gray matter, or surface based?
I am sorry if my questions is basics, I don't have good experience in freesurfer so I want to be sure that I am using the correct terms.
Thanks you for any advice! John
