Assessing internal carotid artery stenosis with a semiautomated computed tomography angiography tool and duplex ultrasound

Duplex ultrasound (DUS) and computed tomography angiography (CTA) are both used as first-line noninvasive methods to investigate patients for internal carotid artery (ICA) disease. Although manual assessment of CTA is well established, semiautomated vessel analysis programs have yet to prove their clinical benefit. We compared one such vessel analysis program (TeraRecon, Foster City, Calif) with DUS.A total of 85 arteries in 50 patients (35 men,...
