What Is a Carotid Doppler Scan?

A carotid Doppler scan is a non-invasive ultrasound examination of the carotid arteries — the major blood vessels on either side of your neck that carry blood from your heart to your brain.

This scan uses Doppler technology to measure the speed and volume of blood flow through these arteries. It can detect plaque build-up (atherosclerosis), narrowing (stenosis), and other abnormalities that may increase your risk of stroke.

What We Assess With This Scan

  • Common carotid artery (on both sides)
  • Internal carotid artery (supplies blood to the brain)
  • External carotid artery (supplies blood to the face and scalp)
  • Plaque: Amount, location, and characteristics of any fatty deposits
  • Stenosis: Degree of narrowing in the arteries
  • Blood flow: Speed and volume of blood flow using Doppler technology

This scan cannot assess:

  • Blood vessels inside the brain itself
  • The exact cause of existing neurological symptoms
  • Whether you will have a stroke (it assesses risk factors only)

Why You Might Need This Scan

Common symptoms:

  • •Previous stroke or transient ischaemic attack (TIA/mini-stroke)
  • •Dizziness or balance problems
  • •Temporary vision changes
  • •Weakness or numbness on one side of the body
  • •High cholesterol or cardiovascular disease
  • •Family history of stroke or carotid disease

Conditions we assess:

  • •Atherosclerotic plaque (fatty build-up)
  • •Carotid artery stenosis (narrowing)
  • •Increased risk of stroke or TIA (mini-stroke)

What to Expect

Before Your Scan

No special preparation is needed. You can eat, drink, and take your medications as normal.

Preparation checklist:

  • Wear a top with an open or easily accessible neckline
  • Remove necklaces or jewellery from the neck area
  • Arrive 10 minutes before your appointment time

During the Scan

You'll lie comfortably on an examination table with your head slightly elevated. The sonographer applies warm gel to your neck on both the right and left sides. A handheld probe (transducer) is gently moved across your neck to capture images of the carotid arteries. You will hear the sound of blood flowing as the sonographer takes measurements — this "whooshing" sound is the Doppler signal detecting blood movement. The scan typically takes 20-30 minutes.

After Your Scan

You can return to normal activities immediately. There are no restrictions or downtime.

Results & Next Steps

Your scan is reviewed by a consultant radiologist, who prepares a formal report. This report is sent to your referring doctor within 2-3 working days. Your GP will discuss the results with you and advise on any follow-up or treatment needed.

Frequently Asked Questions

No — a carotid Doppler scan is completely painless. You may feel light pressure as the probe moves across your neck, and you'll hear the sound of blood flow during the examination.
The scan usually takes 20-30 minutes. Please allow additional time for check-in.
A GP referral is recommended as it provides useful clinical context and ensures results are sent to the right person. However, please contact us if you don't have one.
Plaque is a build-up of fatty deposits, cholesterol, and other substances in the artery walls. While some plaque is common as we age, significant build-up can narrow the arteries and increase stroke risk. Early detection allows for management through lifestyle changes and/or medication.
Your images are reviewed by a consultant radiologist and a formal report is sent to your referring doctor within 2-3 working days.
Yes. Ultrasound uses sound waves (not ionising radiation) and is considered very safe.
If moderate to severe stenosis is detected, your GP may refer you to a vascular specialist for further assessment. Treatment options may include medication, lifestyle changes, or in some cases, surgical intervention.
Coverage varies by insurer and your individual policy. Please check directly with your provider.
