First your physician conducts a physical exam. During your exam, your physician will listen for sounds of turbulent blood flow in your carotid arteries. He or she may also measure your blood pressure. If your physician suspects you have carotid artery disease, a carotid duplex ultrasound study will be ordered. In this painless test, a technician holds a small ultrasound probe to your neck. The probe emits high-frequency sound waves that bounce off of blood cells and blood vessels to show blood flow and problems with the structure of blood vessels. This test can show your physician how open your carotid arteries are and how quickly blood flows through them. Carotid duplex ultrasound detects most cases of carotid disease. However, if ultrasound does not provide enough information, your physician may order an Angiogram, a CT Angiography (CTA) exam or a Magnetic Resonance Angiograpy (MRA).
