Correlation between US-PSV and 64-Row MDCTA with Advanced Vessel Analysis in the Quantification of 50–70% Carotid Artery Stenosis
Figure 3
Left carotid stenosis demonstrated on CT angiography (CTA) (Case 1) 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. (c) regular cross-sectional image with the largest/smallest luminal diameter at the stenosis level. In this case the measurements on CTA show a minimum diameter of 2,4 mm with a 79% of stenosis degree. (d) Axial amage of left carotid artery.
