Figure 5.

Right carotid stenosis demonstrated on CT angiography (CTA) (Case  2) with curved image (a) and lumen image produced by Advanced Vessel Analysis (AVA) software (b). The curved image shows the plaque. The software analysis defines automatically the level of maximal stenosis. Regular cross-sectional image showing the diameter at the stenosis level (c). In this case the measurements on CTA shows a minimum diameter of 3,6 mm with a 58.4% of stenosis degree. Volume rendering showing the right internal carotid artery (d).
