Hi,
I want to look at longitudinal change, possibly using siena. What I have is
the following:
At timepoint 1
1) A 3D T1W scan
2) Another scan, registered to the 3D
At timepoint 2
1) A 3D T1W scan
2) Another scan, registered to the 3D
I am interested in the difference between the scans registered to the 3D.
However, I cannot directly compare these, as I expect that atrofy has
occured. What I would like to do is to apply something like the inverse
atrofie matrix, such that I can compare the registerd scans, look for
differences, but discarding the differences that are a consequence of the
atrofy.
Is a scheme like this possible with siena and related tools?
Thanks,
Erik-Jan Vlieger
