Validation of Multiparametric Ultrasonography Criteria with Digital Subtraction Angiography in Carotid Artery Disease: A Prospective Multicenter Study

What can we learn from this paper by Barlinn et al. [1] and what does it add to our ability to treat patients with carotid artery disease? The authors stated that their aim was to validate the DEGUM consensus for multiparametric grading of carotid stenosis [2]. Years ago when only CW Doppler sonography was available, the positive predictive value for occlusion of the ICA, if diagnosed by well-trained investigators, was about 90 %. This paper...
