| Research Abstract |
The purpose of the present study is to elucidate the role of hemodynamics in atherosclerosis by experimental induction of atherosclerotic plaque in the swine carotid artery. Complex atherosclerotic plaque was successfully induced in the lesion distal to surgical partial ligation. Systolic and diastolic flow velocity were obtained with phase contrast sequence in 3.0 Tesla MRI. Wall shear stress was calculated with the obtained dataset. Shear stress was maintained high in the lesion distal to surgical partial ligation due to unidirectional jet flow. By contrast, in the lesion proximal to ligation, shear stress was found to oscillate during cardiac cycle. Low wall shear stress may contribute to plaque formation in this animal model.
