Coregistration of Wall Shear Stress and Plaque Distribution within the Thoracic Aorta of Acute Stroke Patients

Fig. 1: Strategy for the evaluation of wall shear stress parameter distribution in the aorta (A) and at the site of complex plaques (B, C). A: 3D-PC-MRA was used to position 8 standardized analysis planes in the ascending aorta (AAo, 1-3), aortic arch (4-5), and descending aorta (DAo, 6-8) for the calculation of segmental WSSmag and OSI. B: For 144 complex plaques, images depicting maximum plaque thickness were fused with the 4D flow data. D: A standardized 12 segment model was employed for a direct one-to-one correlation of plaque location and wall parameters.
