Hi all, I am wondering if partial volume is taken into account when calculating average uptake values of pet data. I know that aseg.stats takes partial volume into account and I am wondering if there is something similar in place for pet data? From what I gather, most people when using FreeSurfer correct for partial volume effects by regressing out cortical thickness, but no basis for this correction method has been provided. Any insight would be appreciated.
n.b. to obtain the pet uptake values I used mri_segstats --seg mri/aparc+aseg.mgz --sum pet.segstats.dat --i $petanat --ctab rois.txt Thank you, Corinna
