According to the US National Institute of Neurological Disorders and Stroke, incidence of reported intracranial aneurysm (IA) rupture is about 0.001%. In other words, there are thus about 27,000 people who may suffer stroke from ruptured cerebral aneurysms each year. The origin and natural history of IAs are closely associated with disturbed hemodynamics though exact mechanisms are unknown.[1, 2] Consequently, blood flow parameters measured from phase-contrast magnetic resonance imaging (PC-MRI) [3, 4] may provide insight not only into factors relevant to the development and progression of IAs but also into their short and long term responses to therapeutic interventions (e.g. coil embolization and stent deployment).
