What Is Colour Doppler?
Colour Doppler is a kind of ultrasound test that looks at how blood flows through vessels in your body—like arteries and veins. Unlike a regular ultrasound that shows structure (organs and tissues), Colour Doppler shows moving blood and its speed, direction, and whether there’s any trouble. It adds “colour” to the image, so doctors can see where blood is flowing normally and where it might be blocked or slowed.
Think of it like a map with traffic colors: red might mean blood is flowing toward the probe, blue means away, and the mix tells the doctor about possible “traffic jams” in the vessels.
Why Do Doctors Use Colour Doppler?
Doctors may order a Colour Doppler test for many reasons, because it gives important clues about your blood flow and vessel health. Some reasons include:
- To check for blockages or narrowing in blood vessels (for example, in the neck or legs). This is especially important in conditions like stroke, where timely detection of reduced or blocked blood flow can save lives.
- To see if there is poor circulation to organs or limbs.
- To evaluate veins when there’s suspicion of clots (deep vein thrombosis).
- To monitor blood flow in the heart or around it (in combination with a heart ultrasound).
- To see how blood is reaching transplanted organs or grafts.
- To check vessels in the kidneys, liver, or elsewhere in certain conditions.
Doctors in competing imaging centers also use Colour Doppler because it’s non-invasive and gives real-time results.
How Is a Colour Doppler Done?
The process is simple and painless. Here’s how it usually goes:
- You lie down on an examination table.
- A gel is applied to the area of your body to be scanned (like your neck, legs, abdomen, etc.). This gel helps the sound waves pass better.
- A small device called a probe is gently moved over the skin. It sends sound waves and listens to returns (echoes).
- The machine detects the echoes and overlays color to show blood flow. You’ll see moving colors on the screen.
- The technician or doctor watches and records images, may ask you to hold breath or change position for better views.
- The scan typically takes about 15–30 minutes, sometimes a bit more if many areas are checked.
You don’t feel pain; you might feel slight pressure from the probe.
Benefits of Colour Doppler
- Safe and painless: No radiation, no cuts.
- Quick results: Doctors can often interpret flow immediately.
- Early detection: Helps find circulatory issues before they become serious.
- Non-invasive: You don’t need needles or surgery.
- Versatile: Can assess many parts of the body—legs, neck, heart, organs, vessels.
- Guides treatment: Helps decide if interventions like stents, medications, or surgery are needed.
Preparation Before the Test
To get good results from a Colour Doppler, a few simple steps help:
- Wear loose, comfortable clothes so the technician can access the area easily.
- You might be asked not to eat or drink for a few hours before abdominal Doppler scans.
- For vascular scans of limbs, avoid tight clothing, do not apply lotions or creams on skin.
- Carry prior ultrasound or imaging reports, if any, so doctors can compare.
- Follow any instructions your doctor gives—like fasting or holding water in the bladder, depending on the area.
At Aditya Birla Memorial Hospital, staff will guide you ahead of time about preparation so you know exactly what to do.

1. Does Colour Doppler hurt?
No, it doesn’t hurt. You might feel light pressure as the probe moves, but nothing painful.
2. How long does the test take?
Usually about 15 to 30 minutes, depending on how many areas are scanned.
3. Can I eat before the test?
It depends: for abdominal Doppler scans you may need to fast. For limb or neck scans, you can eat normally.
4. Is this safe during pregnancy?
Yes, Colour Doppler is safe—there’s no radiation. Doctors use it with care near the abdomen.
5. When will I get my results?
Often the radiologist reviews images right away and gives a preliminary report. A full report may take a few hours to one day.
6. Do I need special clothes?
Wear loose, comfortable clothes. You may need to remove tight garments or jewelry near the test area.
