Cerebral aneurysm hemodynamics modeling from 3D rotational angiography

Abstract

Detailed knowledge of the hemodynamics in cerebral aneurysms is valuable not only for understanding their formation and rupture but also for clinical evaluation and treatment. However, important hemodynamic quantities are difficult to measure in vivo. In this paper a patient-specific method for modeling the hemodynamics of cerebral aneurysms from in vivo anatomical images is described, and the flow patterns in various kinds of intracranial aneurysms are presented. These models will be used to explore possible relationships between the blood flow patterns and the location, size and taxonomy of the aneurysms.
