Hi there,

I know in the past, it was recommended to acquire 2 T1 scans so that they
could be averaged for better SNR, etc. in order to improve cortical
thickness and surface area measurements. Is this still the recommendation?
We have a few extra minutes in our scanning protocol and are debating
whether to include a 2nd T1.

Our parameters are: MPRAGE with .8mm^3 voxel size, slice thickness of .8,
FA = 8 degrees, TR = 2400ms, TE = 2.72ms, TI = 1060ms.
