Carotid Duplex Ultrasound
Carotid artery disease occurs when the major arteries in your neck become
narrowed or blocked. These arteries, called the carotid arteries, supply your
brain with blood. Your carotid arteries extend from your aorta in your chest to
the brain inside your skull.
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.
After the history and exam, if your physician suspects you have carotid
artery disease, he or she will perform a
carotid duplex ultrasound. 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
Carotid duplex ultrasound detects most cases of carotid artery disease.
Therefore, your physician usually may not need to perform other tests.
