Posting some images somewhere might illuminate the problem.

Subject: [FSL] Subtracting Images: Lesion Analysis
Hello FSLers,
We would like to compare baseline and exit lesions using T2, T2 Flair, and
FSPGR scans. We are trying to use a subtraction method, but our method
doesn't seem to be working very well. We have been working in the halfway
space produced by siena. We are normalizing the images as well. Then, the
baseline is subtracted from the exit; however, the subtraction is not useful
even when altering the contrast in the FSLviewer.
Currently, we are stuck comparing the two registered images in the halfway
space from siena.
Any help will be appreciated.
Thank you,
Alex
