Re: [Freesurfer] Overestimation of volume in Hippocampus

Hi Michel Hu, Is that a summed value of left and right hippocampus? That seems normal to me since averaged total hippocamppal volumes for MCI have been typically reported at around 2500-3500mm3. Thanks, --  Shane S On 27 February 2017 at 09:44:27, Michel Hu (a...@live.nl) wrote: Dear Freesurf
