Carotid Duplex Scan
Carotid duplex ultrasonography is a test used to examine the two carotid arteries in your neck. The purpose of this scan is to detect blockages or narrowing of the arteries that could lead to stroke. Additionally, your doctor may use this test to examine the vertebrobasilar artery which also brings blood into the brain.
During the scan, the transducer will create high-frequency sound waves that will map out your arteries. With the data produced from the ultrasonic waves, the transducer will visualize your veins so your doctor can provide an accurate diagnosis.
After the first test, we will monitor the condition of your arteries as you progress through treatment. In particular, we will use the duplex scan to follow patients with carotid artery disease or previous patients who received surgery or stents to correct carotid blockage. We encourage all of these patients to come in for regular scans to ensure their health and well-being.
Who is a Carotid Duplex Scan For?
This examination is common for patients with symptoms such as Transient Ischemic Attack, a frank stroke, neck masses which may represent a carotid artery tumor, asymptomatic bruits, and/or non-hemispheric symptoms such as dizziness, syncope, or double vision.
