Hi Sasha,
the standard deviation across the surface isn't a very meaningful number,
since the thickness isn't spatially stationary.
cheers,

Dear all,
I am interested in measuring mean thickness within ROI in MPRAGEs of
children. My mean thickness values tend to be around 3.3 mm, with a
standard deviation of about 1mm. I am concerned that these standard
deviations are somewhat high. What typical values should I be expecting
for standard deviation?
Thanks,
Sasha
