not really. It is more of a question of whether the GTM or MG models are appropriate (ie, constant signal in an ROI). MG probably better than GTM because it makes fewer assumptions.

Hello Doug,
Thanks for replying. Anything I should watch out for when using it for Tau processing?
Thanks.
Best, Paul

Hello FreeSurfer,
I would like to know if mri_gtmpvc for PetSurfer is appropriate for Tau (AV_1451) and FDG pet imaging. Also, is cerebellum a good reference point for both tracers?
Thanks. Paul
