About doppler ultrasound

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 during a doppler ultrasound? icon plus

    Your scan will take approximately 15 to 30 minutes and will be carried out by one of our specialist vascular scientists.

    Gel will be applied over the area of skin that will be examined, and as the scan starts, a transducer (a handheld device) will gently press and move over your skin. This action will produce a moving, real-time image of your blood flowing through your blood vessels.

    A recording is taken of the image and then sent off for analysis by one of our expert cardiologists.

  • How to prepare for your scan 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.

  • After your scan 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.
