Patient-specific CFD carotid models may support virtual therapy planning; leaves open prospective outcome validation before clinical use.
Computational fluid dynamics based on medical imaging can successfully model patient-specific carotid bifurcation hemodynamics, offering a potential tool for diagnosis and therapy planning.
Tu et al. (2011) studied Carotid artery stenosis (n=10). Computational fluid dynamics modeling was evaluated on Hemodynamic flow properties (pressure gradient and wall shear stress). Computational fluid dynamics modeling of 10 patient-specific carotid bifurcations demonstrated that the nature and severity of stenosis explain differences in pressure gradient and wall shear stress.
