Typical approaches to patient-specific haemodynamic studies of cerebral aneurysms use image-based computational fluid dynamics (CFD) and seek statistically correlate parameters such as wall shear stress (WSS) oscillatory index (OSI) risk growth rupture. However, have reported contradictory results, emphasizing the need for in-depth multi-modality metric evaluation. In this work, we used in vivo 4D flow MRI data inform vitro particle velocimetry CFD modalities two aneurysm models (basilar tip...
OBJECT The goal of this prospective longitudinal study was to test whether image-derived metrics can differentiate unruptured aneurysms that will become unstable (grow and/or rupture) from those remain stable. METHODS One hundred seventy-eight patients harboring 198 cerebral for whom clinical observation and follow-up with imaging surveillance recommended at 4 centers were prospectively recruited into study. Imaging data (predominantly CT angiography) initial presentation recorded....
There is increasing interest in assessing the role of hemodynamics aneurysm growth and rupture mechanism. The ability to accurately predict risk an can help providing immediate intervention patients with aneurysms at high Also, small but significant associated treatment options be avoided for stable harmless aneurysms. Retrospective studies have been performed past identify indices that differentiate ruptured from unruptured [1–3]. However, these differences may not necessarily translate...

In this work, we conducted tomographic particle velocimetry using two aneurysm models (basilar tip internal carotid artery)...
