The Doppler Ultrasound is a test that uses ultrasound to assess the blood flow through your arteries and veins. It is a risk-free and pain-free procedure. The transducer sends sound waves through your skin and other body tissues to the blood vessels. The sound waves echo off of your blood vessels and send the information to a computer to be processed and recorded. The computer will produce graphs or pictures that show the flow of the blood through your arteries and veins.
Why is a Doppler Ultrasound performed?
The Doppler ultrasound exam may be ordered if you show signs of:
- A blood clot forming in a vein deep inside your body
- An inflammation of the veins due to a blood clot in a vein just below the skin’s surface
- Varicose veins and incompetent valves of the blood vessels.
- Narrowing and hardening of the arteries that supply blood to the legs and feet
- Vascular tumours
What Happens During a Doppler Ultrasound?
- You will need to remove clothing, jewellery, and any other objects in the area that will be studied and may be asked to wear a hospital gown.
- You’ll be instructed about the position depending on the part to be assessed.
- A water-soluble gel will be put on a transducer, which directs high-frequency sound waves into the arteries or veins being studied.
- Images are taken as the transducer is moved along the part being studied. You may hear a “whooshing” sound as blood flow is detected.
