Assessing the risk of rupture of cerebral aneurysms is important for planning elective interventions. Since hemodynamics is thought to play a fundamental role in the mechanisms governing aneurysm progression and rupture, numerous investigations have tried to connect aneurysm hemodynamic conditions and rupture. In our previous work aneurysm flow patterns were qualitatively classified into simple / complex and stable / unstable categories by looking at the number of vortices within the aneurysm and their persistence during the cardiac cycle [1, 2]. The purpose of this work is to propose objective hemodynamic metrics that can capture these flow characteristics with the goal of relating them to aneurysm rupture.
