A carotid Doppler test in Delhi is a quick, painless ultrasound of the two large arteries in your neck (the carotid arteries) that carry blood to your brain. It checks whether these arteries are narrowed or blocked by plaque and how well blood is flowing through them — information that helps assess your risk of stroke. At Edge Imaging & Diagnostics in Paschim Vihar, West Delhi, the carotid Doppler is performed on high-resolution colour Doppler ultrasound for accurate, reliable results.
This guide explains what a carotid Doppler is, why it is done, who needs it, and what to expect.

What Is a Carotid Doppler Test?
A carotid Doppler is a colour Doppler ultrasound that looks at the carotid arteries on each side of the neck. Ordinary ultrasound shows the wall and structure of the artery, while the Doppler part measures the speed and direction of blood flow. Together they reveal any build-up of fatty plaque (atherosclerosis), the degree of narrowing (stenosis), and whether blood flow to the brain is affected — all without any needle, dye or radiation.
Why Is a Carotid Doppler Done?
The carotid arteries are a common site for plaque build-up, and a significant narrowing here is an important and treatable cause of stroke. A carotid Doppler helps to:
- Assess stroke risk by detecting and grading carotid narrowing
- Find the cause of a TIA (mini-stroke) or stroke
- Investigate a bruit (an abnormal sound your doctor hears over the neck)
- Follow up known carotid disease or monitor after carotid surgery/stenting
Who Should Get a Carotid Doppler?
Your doctor may advise a carotid Doppler if you have had stroke-like symptoms (sudden weakness, slurred speech, facial droop, temporary loss of vision) or if you have risk factors for artery disease, such as:
- High blood pressure, diabetes, or high cholesterol
- Smoking or a strong family history of stroke or heart disease
- Known coronary artery disease or peripheral artery disease
- A neck bruit found on examination, or planning before major surgery
| Carotid Doppler checks | What it shows |
|---|---|
| Artery wall & plaque | Fatty build-up and its type |
| Degree of narrowing | Mild, moderate or severe stenosis |
| Blood-flow speed | How much flow is reduced |
| Direction of flow | Normal or reversed flow |
How the Carotid Doppler Is Performed
The test is simple and comfortable. You lie on your back with your head slightly turned. A little gel is applied to your neck and the radiologist moves the ultrasound probe gently over each side, capturing images and flow measurements. It usually takes about 20–30 minutes. There is no injection, no radiation and no discomfort, and you can go back to normal activity immediately.
Is It Safe and Do I Need Any Preparation?
The carotid Doppler is completely safe — it uses only sound waves. No fasting or special preparation is needed; you may be asked to avoid a high polo-neck collar so the neck is easy to access. It is part of our wider ultrasound and colour Doppler services, which also include the penile Doppler and other vascular studies.

How much does a carotid Doppler test cost in Delhi?
A carotid Doppler in Delhi generally costs about ₹1,500–₹3,000 depending on whether one or both sides and additional vessels are studied. Edge Imaging offers transparent pricing — please call us for the current cost.
Is the carotid Doppler painful?
No. It is completely painless — just a probe and gel moved over your neck, with no needle, dye or radiation.
Do I need to fast or prepare?
No fasting is needed. Simply wear something with an open neckline so the area is easy to scan.
How long does the test take and when do I get results?
The scan takes about 20–30 minutes, and the report is usually available the same day.
Can a carotid Doppler prevent a stroke?
It cannot prevent a stroke by itself, but by detecting significant narrowing early it lets your doctor start treatment — medicines, lifestyle changes, or a procedure — that can substantially reduce your stroke risk.
