a) 3D WSS throughout aortic surface, b) 10 regions used for segmental WSS analysis along the thoracic aorta: 1 = proximal inner AAo, 2 = proximal outer AAo, 3 = distal inner AAo, 4 = distal outer AAo, 5 = inner arch, 6 = outer arch, 7 = proximal inner DAo, 8 = proximal outer DAo, 9 = distal inner DAo, 10 = distal outer DAo, c) Peak systolic velocity maximum intensity projection (MIP) with one erosion. AAo = ascending aorta, DAo = descending aorta
