Hi Timothy
do you have T2 or FLAIR data? Have you looked for the WM and non-WM hypointensity labels in your T1 segmentations? If you have run recon-all you might already have some useful information.

Hello Bruce, Thank you for the quick reply. I performed recon-all on about 140 subjects and my PhD supervisor wanted to know if there was a way to detect black holes. Any way that I could get access to the tools you mentioned?
I am a recent medical school graduate with Master's and undergraduate degrees in computer science. I could help out with documenting/distributing once I get a handle on how those tools work (as thanks :) ).
Regards, Timothy

we do label WM and non-WM hypointensities. Typically they are a lot more apparent on a T2 or FLAIR though (and we have some tools to do this, although they aren't really documented/distributed yet) cheers Bruce On Sat, 25 Mar 2017, Timothy M wrote: Hello, I cannot seem to find any documentation regarding detection of "black holes" on T1WI (e.g., in patients with multiple sclerosis). Does FreeSurfer provide this functionality? If so, is there any documentation on the subject? Thank you, Timothy
