This study demonstrates the potential of using 3D cine PC-MRI in patient-specific models of atherosclerotic carotid disease to provide detailed information of flow patterns and the spatiotemporal dynamics of turbulence intensity. 45 minutes long high-resolution 3D cine PC-MRI scans were performed in patient-specific models of carotid disease under in-vivo mimicking flow conditions. These high-quality MR data permitted visualization and analysis of potential transarterial pathways for emboli, intrastenotic flow features, and the destabilizing effects of flow deceleration.
