Dear experts,
We are designing a study including a long MR protocol:
1) Localizer
2) Cal
3) T1-FSPGR
4) FLAIR 3D
5) DTI 1
6) DTI 2
7) fMRI
Due to patients characteristics we were thinking on splitting the
acquisition in two different sessions (session 1: sequences 1, 2, 3, 4;
session 2: sequence
I think the only thing you would have to worry about is the fMRI since
the way the subject reacts to the task (or state of subject during rest)
might change depending upon how long he/she has been in the scanner. Why
not do the fMRI at #3? Then each population would be in the scanner for

Hi All,
I have run recon-all on a subject with a large cortical dysplasia, and
while the segmentation (aseg) seems to be relatively correct, there is a
large region of dysplasia not included by the pail surface. The normalized
intensity values for the cortex and the excluded region are very simila
Hi,
My understanding of etiv is that it is derived from the registration of a
brain to atlas space and not actually derived from the freesurfer
segmentation. I have a set of patients imaged at 2 time points that all
have different etiv values between the first and second scan that are
statistica
