A cerebral aneurysm (CA) is an abnormal distension of the wall of an artery in the brain, which results from arterial wall weakening. CAs are poorly understood, but are believed to be the result of a combination of biological and life-style factors. The low incidence of rupture coupled with risks of interventional treatments provide motivation for identifying and treating only those aneurysms at risk of rupture. Computational models of aneurysm evolution may provide great insight into CA d...
