Dear FS users, I would like to use FS to calculate WM hypointensitis (so-called black holes) for patients with multiple sclerosis, but

1. I don't know which stat file I should use to report the volumes,

such as total WM, WM hypointensities, etc

Use aseg.stats

2. which editing tool I must use when the lesion is not classified as

WM hypointensities by FS? I know that the control points are not used or recommended for WM lesions

You can use tkmedit as you would for fixing any other area in the aseg volume. Look at the tutorial on this.

3. Can I use other sequences for detecting other classes of lesions

present in this disease, such as hyperintense T2 lesions (T2WI) or enhacing lesions on contrast enhaced MR, in order to calculate the volumes of those, or just the T1 (MPRAGE)

We don't have anything for this yet.

4. which literature do you suggest for the post processing of these

lesions using FS or perhaps another tool?

I'm not the one to ask yet. doug

thanks a lot,

Carolina
