Carotid Duplex SonographyDefinitionCarotid duplex sonography, sometimes called carotid duplex ultrasound, is a non-invasive diagnostic procedure that allows a physician to see the structure of the carotid artery and the way blood is flowing through it. Carotid ultrasonography is an ultrasound-based diagnostic imaging technique to evaluate structural details of the carotid arteries.Carotid ultrasound is used to diagnose carotid artery stenosis (CAS) and can assess atherosclerotic plaque morphology and characteristics. Conventional, or B-mode, ultrasound uses sound waves that bounce off blood vessels to provide a picture of the structure of your blood vessel. 3, Cardiovascular Therapy and Prevention, Vol. They’ll then move a small ultrasound wand along the area where your carotid arteries are located. 23, No. 15, No. If your doctor thinks you have carotid artery disease, they’ll order a carotid duplex scan.
