Correlation between US-PSV and 64-Row MDCTA with Advanced Vessel Analysis in the Quantification of 50–70% Carotid Artery Stenosis
Figure 2
Left carotid stenosis demonstrated on Duplex US (Case 1) (a). Measurements of minimal lumen diameter (b) and Spectral US Evaluation with PSV Measure (c). The data obtained by Duplex US shows a high rate correlation with CTA measurements, with a stenosis of 80% evaluated according to strandness criteria and 79% with advanced vessel analysis (AVA) software at CT angiography.
