Dear AFNI users-

We are very pleased to announce that the new AFNI Message Board framework is up! Please join us at:

Existing user accounts have been migrated, so returning users can login by requesting a password reset. New users can create accounts, as well, through a standard account creation process. Please note that these setup emails might initially go to spam folders (esp. for NIH users!), so please check those locations in the beginning.

The current Message Board discussion threads have been migrated to the new framework. The current Message Board will remain visible, but read-only, for a little while.

Sincerely, AFNI HQ

Hello, I am wondering if anyone has any ideas for removing blood vessel ghosting artifact from T1 structural MRI images.

I have attached a screenshot of the artifact, exaggerated by choosing inappropriate windowing levels.

Essentially, I am looking for a skullstrip-like solution, except that I would like to keep the skull in the images, not just the brain.

Are there existing tools for this?

Cheers,
-Tynan
