Thank you kindly for your prompt response.
I am actually having difficulties with the
delineation of White Matter Hyperintensities at a single time
point. I apologize if my question is redundant and perhaps an
answer to it is already mentioned elsewhere.
As it stands, I am finding it difficult to
understand the exact “pipeline” of commands necessary to
perform this segmentation and accurate delineation of WMH. I
have ran the recon -all command on my T1w images, but I
suspect a proper segmentation of WMH would require a T2w Flair
(which I have). How do I go about combining the preprocessing
data produced by FreeSurfer with my T2w images to produce a
WMH mask/volume/stats?
Any help on the matter is much appreciated!
Kindly,
Navena Lingum
Hi Navena,
There is
currently no dedicated stream for longitudinal WM
abnormalities (in the sense of joint estimation and
modeling). You can, however, make use of the
longitudinal stream and it's increase reliability -
e.g it is working in the same space across time, which
should help get more reliable estimates.
Best,
Martin

Dear FreeSurfer experts,
My colleagues and I would like to use
FreeSurfer to perform a longitudinal analysis of
white matter hyperintensities. Is there an
additional add-on for the software to perform this
analysis or can this analysis be performed using
the recon-all command?
