CFD Simulation of Flow Mixing in the Vertobrobasilar System
Keyword(s):
Patient specific modeling can provide detailed hemodynamic information that is not available through most standard imaging modalities. The vertebrobasilar system is comprised of the confluence of the two vertebral arteries into the basilar artery, followed by divergence into the posterior cerebral arteries. A pilot study, by Kansagra and Wong [2], utilized vessel-encoded arterial spin labeling, an experimental MRI technique to quantify vertebrobasilar perfusion. In this method, flow in different vessels can be tagged, and perfusion of tagged flow to different regions of the brain can be quantified. These results demonstrated that blood delivered to the right hemisphere came primarily from the right vertebral, and vice versa.
