Does a carotid ultrasound prevent a stroke?

The ultrasound itself does not prevent stroke. It provides information that may help identify plaque or narrowing in the carotid arteries so you and your healthcare provider can make informed decisions about your care.

Does the test use radiation?

No. Carotid ultrasound uses sound waves and does not expose you to radiation.

No. The exam is non-invasive and painless. Most patients describe it as comfortable and quick.

How long does the appointment take?

Most carotid artery ultrasounds are completed in about 20 to 30 minutes.

What happens if plaque is found?

Your physician will review your results and may recommend additional evaluation, lifestyle modifications, medications, or continued monitoring depending on your individual situation.

Carotid Artery Ultrasound in Phoenix

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.

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.

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.

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.

At Life Guard Imaging, we believe preventive health starts with information.

Our carotid artery ultrasound is performed using advanced ultrasound technology and interpreted by experienced physicians who carefully evaluate your images.

If abnormalities are identified, your results can be shared with your primary care physician or specialist to help guide any recommended next steps.

Combined with our preventive imaging services, including heart scans and full body CT scans, carotid ultrasound provides another valuable way to better understand your cardiovascular health.
