Hi Heather,
I think the answer is that we don't really know. Hopefully the level at
which we cut off the brainstem is consistent as it's based on the curvature
of the enclosing surface that we fit, but we've never looked at it
thanks

I was wondering if Freesurfer has a standard way of cutting off the measurement
of brain stem volume across subjects, or does the volume of the brain
stem depend on the individual?s skull strip? In the two examples below, you
can see that the brain stem of the second individual extends beyond that
of the first (visually and according to its aseg label). Theoretically, could
the reported volumes of these two individuals? brain stems be different
just because their skull strip was different?
Thank you,
Heather
