Doppler ultrasound scan

Imaging test that shows blood flow

Find out about our Doppler ultrasound tests, which can help to diagnose a range of heart and blood problems

About

A Doppler ultrasound scan can be used to create a real-time image of blood flowing through your blood vessels. It does this by bouncing sound waves off the red blood cells in your body. It's a non-invasive test, which means we won't need to make a cut in your skin or inject something into you.

Doppler imaging scans can help to diagnose various conditions, including:

- bulging (aneurysm) or blocked (arterial occlusion) arteries
- poor function in your leg vein valves (venous insufficiency)
- heart valve defects and congenital heart disease
- reduced blood circulation in your legs (peripheral artery disease)
- narrowed arteries
- artery injuries
- blood clots

Need to know

  • What happens icon plus

    Your scan will take 15 to 30 mintues. It will be carried out by one of our specialist vascular scientists. They'll start by applying gel over the area of skin that they'll be examining. They'll then start the scan by gently pressing and moving a transducer (a handheld device) over your skin. This will produce a moving, real-time image of your blood flowing through your blood vessels. A recording of this image will be sent off for further analysis by one of our expert cardiologists.
  • How to prepare icon plus

    Usually, there isn't any special preparation needed for a Doppler scan. Your consultant will explain the procedure to you and answer any questions you may have.
  • Afterwards icon plus

    The scan itself shouldn't be painful, and you'll be able to go home immediately after your appointment. Once your consultant has analysed the results of your scan, they will discuss them with you. They'll also let you know about any next steps, including further tests if needed.
