Abstract

The phase 3 of the cerebral aneurysm detection and analysis (CADA) challenge involved rupture risk estimation of intracranial aneurysms using computational methods. In this work we performed computational fluid dynamics (CFD) on a subset of aneurysm cases provided by the challenge committee. A large number of aneurysm cases were available, CFD analysis using the lattice Boltzmann method (LBM) were performed on 18 of them. These 18 aneurysms were chosen on the basis of most distinct shape, size and location. Direct numerical simulations were performed to identify wall shear stress and pressure, and associate these hemodynamic quantities with the rupture status of aneurysms and eventually extrapolate those findings to other aneurysms. The results of the DNS may serve as inputs for data driven methods to identify qualitative maps of hemodynamic quantities in aneurysms. In this article we report the results of CFD and discuss hypotheses associating the flow characteristics with the rupture risk of aneurysms.
