Why Your Carotid Arteries Matter

When most people think about heart health, they focus on the heart itself. But the arteries leading to your brain are just as important.

Your carotid arteries are two major blood vessels located on each side of your neck. They deliver oxygen-rich blood from your heart to your brain. Over time, these arteries can develop plaque buildup, causing them to narrow—a condition known as carotid artery disease.

Because carotid artery disease often develops without symptoms, many people don't realize they have it until it has progressed. A carotid artery ultrasound is a safe, non-invasive way to evaluate these arteries and provide valuable information about your vascular health.

What Is a Carotid Artery Ultrasound?

A carotid artery ultrasound is an imaging exam that uses sound waves to create detailed pictures of the carotid arteries in your neck.

Unlike CT scans or X-rays, ultrasound uses no radiation. During the exam, a trained ultrasound technologist gently moves a small handheld device over your neck while images of your arteries are captured in real time.

The test is painless, non-invasive, and typically takes less than 30 minutes.

What Can a Carotid Ultrasound Detect?

A carotid ultrasound helps evaluate blood flow and can identify changes within the arteries that may increase the risk of stroke or other vascular conditions.

The exam may detect:

• Plaque buildup within the carotid arteries
• Narrowing of the arteries (carotid stenosis)
• Changes in blood flow
• Areas that may require additional evaluation by your healthcare provider

Finding plaque early doesn't necessarily mean a procedure is needed. In many cases, the results can help guide conversations about lifestyle changes, medications, or ongoing monitoring with your physician.

Why Is Plaque Buildup Important?

Plaque is made up of cholesterol, calcium, fat, and other substances that gradually accumulate inside artery walls.

As plaque grows, it can reduce blood flow to the brain or become unstable. If a piece of plaque breaks away or a blood clot forms, it can block blood flow to the brain and cause a stroke.

The good news is that plaque buildup often develops gradually over many years. Identifying it early provides an opportunity to work with your healthcare provider on strategies that may help reduce future cardiovascular risk.

Who Should Consider a Carotid Artery Ultrasound?

A carotid artery ultrasound is not recommended as a routine screening test for every adult. However, it may be appropriate for individuals who have certain cardiovascular risk factors or who have been advised by their healthcare provider to undergo vascular screening.

You may benefit from discussing carotid ultrasound with your healthcare provider if you have:

• High blood pressure
• High cholesterol
• Diabetes
• A history of smoking
• A family history of stroke or vascular disease
• Known coronary artery disease
• Peripheral artery disease
• A previous transient ischemic attack (TIA) or stroke
• A carotid bruit (an abnormal sound heard through a stethoscope)

Every person's health history is different, which is why screening decisions should be individualized.

What Happens During the Exam?

Your carotid ultrasound is simple and comfortable.

During your appointment:

• You'll lie comfortably on an exam table.
• A clear gel is applied to your neck.
• The ultrasound technologist gently moves the transducer over both sides of your neck.
• Images of your carotid arteries are recorded.
• The exam is completed in approximately 20–30 minutes.

There are no needles, no injections, no recovery time, and you can return to your normal activities immediately afterward.
