It should not have changed the WM volume. Did you happen to see the
thread about a bug in mri_segstats? It could be causing this. You can

The only thing that we have that comes close to quantifying lesions is
the volume of WM hypointensities. This will likely underestimate the
lesion volume by a lot.
