Important message from Kerri on the "central vein sign" seen on 7T MRI. The vascular connection is real.

Has anyone ever asked you what MS has to do with veins? Show them these 7T MRI pictures:

"7T reveals a central black dot at the center of nearly all lesions (arrow in the upper image shows one example), which represents the effects of blood flow in a central vein. This association is well established from microscopic pathology, and it can now be demonstrated on MRI with the advent of 7T."
