MR-based computational fluid dynamics with patient-specific boundary conditions for the initiation of a sidewall aneurysm of a basilar artery

Magn Reson Med Sci. 2015;14(2):139-44. doi: 10.2463/mrms.2014-0003.

Abstract

We performed 3-dimensional cine phase-contrast magnetic resonance-based computational fluid dynamics for a basilar artery that developed a sidewall aneurysm over a 25-month period. There was an area with high gradient oscillatory number in the location of the future aneurysm ostium and an area with high wall shear stress (WSS) and high spatial WSS gradient at the distal edge of the future aneurysm. These could be biomarkers for development of intracranial aneurysms.
