Hi all,
Could it be a problem in FreeSurfer longitudinal analysis if I use two
different sequences (T1 MP2RAGE and T1 MPRAGE) for different time
points/follow-ups?
Thanks for the support,
Sara

yes, it will be much more sensitive/specific. Note that you have to run
the cross-sectional first in any case though

Dear all,
I’ve just started using FreeSurfer and I need your advice. I have two series of
images made 1 year apart from each other. Is it correct to use a Longitudinal

Hello Gabor,
a few quick comments:
i) Although we typically aim for maximizing both, accuracy and
reproducibility are different things. In a longitudinal study you are
often particularly interested in the reproducibility of the findings, in
the sense of their repeatability across different ti
I've found the article "Within-subject template estimation for unbiased
longitudinal image analysis" by Reuter et al. It only examines a limited
number of structures for the reproducibility of longitudinal Freesurfer.
Are there any other paper that examines the cerebellum as well? Any
suggestion fr
Dear all,
We've run longitudinal Freesurfer on 30 healthy subjects. We have two
subgroups (n=15) and we found a significant longitudinal change in the left
and right cerebellar cortex in one of our subgroups. However, this change
is very small: mean=0.67% range: -1.61-2.3% for the right cerebellar
Hi,
I want to use FreeSurfer to analyze a longitudinal study. For each
subject in my study, I already used FreeSurfer 4.2 to perform the
cross-sectional analysis. However, FreeSurfer 4.2 did not have a
longitudinal pipeline. Therefore, I want to use FreeSurfer 4.5 for
this purpose (in the FreeSurfe
