Carotid duplex ultrasound is a painless, non-invasive procedure used in the diagnosis of stenosis, thrombosis, arterial occlusion and carotid occlusive disease.
Dignity Health Heart and Vascular Institute of Greater Sacramento provides exceptional diagnostics for our heart and vascular patients. Our physicians use the latest technology to ensure an accurate diagnosis so we can provide you with the best course of treatment available.
Carotid duplex is a procedure that uses ultrasound to look for plaques, blood clots, or other blood flow problems in the carotid arteries. The carotid arteries are located in the neck and supply blood to the brain.
The test combines traditional ultrasound with Doppler ultrasonography. Regular ultrasound uses sound waves that bounce off blood vessels to create pictures. Doppler ultrasound records sound waves reflecting off moving objects, such as blood, to measure how they flow.
