Carotid Ultrasound & Doppler Testing (IMT)


Using high-frequency sound waves called Doppler testing, a carotid ultrasound provides an image of blood flow between the heart and the brain. It helps with the early detection of narrowed arteries and provides information that can reduce the risk of heart attack and stroke.

A related test called a carotid IMT (intima-medial thickness) can help predict the risk of a future cardiovascular event, like a heart attack, and can help your cardiologist develop a treatment plan to avoid one.

Similar to other types of ultrasounds, a carotid ultrasound examines only the carotid arteries, the pathways for blood flow between your heart and brain located on either side of the neck. Plaque build-up can narrow these arteries and if they become blocked, you may experience a stroke.

A carotid ultrasound is painless and typically takes around 30 minutes to complete. Using a transducer, a technician will gather data about your blood flow using Doppler testing, a high-frequency sound wave that bounces off of red blood cells. It’s far more detailed than a traditional ultrasound and will display images on a monitor. In some cases, a carotid intima-media thickness (CIMT) test may also be completed to evaluate the thickness of the artery’s inner layers.

Narrowed blood vessels can be extremely dangerous and lead to a host of medical emergencies, so it’s important to have a carotid ultrasound completed if you’re at risk of cardiovascular disease. This procedure can also help to locate blood clots, detect artery abnormalities, and evaluate the success of certain surgeries. Once a carotid ultrasound has been completed, your cardiologist will use the data to develop a treatment plan.
