What Is a Carotid Duplex Ultrasound Scan Used For?

Carotid Duplex Ultrasound Scan Dealing with any type of vascular disease can be overwhelming. In order to implement an effective treatment option, it is vital that the condition or disease is properly diagnosed. One of the most effective ways to diagnose various conditions is through the use of a carotid duplex ultrasound scan. Here is what you should know.

Why Are Carotid Arteries So Important?

The carotid arteries are critically important as major blood vessels in the neck that supply oxygen-rich blood to the front part of the brain. Even a brief interruption in oxygen flow can result in damage to this area of the brain, which is where speech, personality, sensory, motor functions, and thinking occur. A carotid duplex ultrasound scan evaluates these arteries to diagnose atherosclerotic plaque morphology or carotid artery stenosis.

Why Is the Test Called a Carotid Duplex Ultrasound Scan?

The carotid duplex ultrasound scan is a combination of two kinds of ultrasound in one: a traditional ultrasound and a Doppler ultrasound. The traditional ultrasound converts object echoes into visual images, while the Doppler ultrasound calculates the speed and direction of moving objects. This allows the carotid duplex ultrasound scan to detect both narrowing arteries and areas of reduced blood flow concurrently.

Why Would a Doctor Recommend a Carotid Duplex Ultrasound Scan?

There are several reasons why we may opt for a carotid duplex ultrasound scan. These include:

  • Detecting abnormalities, blockages, or narrowing of carotid arteries: Any of these issues can have devastating effects if left untreated, which makes detecting and diagnosing the condition in a timely manner imperative. A carotid duplex ultrasound scan makes this possible.
  • Evaluating blood flow: The Doppler ultrasound portion of the carotid duplex ultrasound scan assesses the velocity and direction of blood flow to help identify potential blockages.
  • Monitoring disease progression: For patients with known carotid artery disease, the carotid duplex ultrasound scan can monitor progression over time, which helps determine treatment strategies.
  • Evaluating other symptoms: In patients experiencing symptoms like dizziness, slurred speech, blurred vision, or other sides of a stroke or TIA, a carotid duplex ultrasound scan can help determine if the carotid arteries are a source of the problem.
