We have translated a 7T MRI vessel wall imaging protocol for assessing intracranial vessel wall morphology to a clinically-available 3T MRI sequence without the need for contrast administration. We have performed this protocol on both young, healthy volunteers as well as on patients with moyamoya disease. Our results indicate that it is possible to discern the vessel wall of young, health individuals with our parameters, and that we can reliably identify the major arteries of the Circle of Willis as well as arteries distal to it.
