The purpose of our study was to demonstrate the feasibility of using patient-specific 3-D rotational angiography (3DRA) image data from clinical studies to construct corresponding realistic patient-specific computational fluid dynamics (CFD) models of cerebral aneurysms. Using these models, the intra-aneurysmal flow patterns are characterized and their possible associations to the clinical history of aneurysmal rupture are explored. Finally, these models are used to analyze the alterations in the flow dynamics precipitated by endovascular procedures.
