A Doppler ultrasound is a noninvasive test that can be used to estimate the blood flow through your blood vessels by bouncing high-frequency sound waves (ultrasound) off circulating red blood cells. A regular ultrasound uses sound waves to produce images, but can’t show blood flow.

A Doppler ultrasound may help diagnose many conditions, including:

  • Blood clots
  • Poorly functioning valves in your leg veins, which can cause blood or other fluids to pool in your legs (venous insufficiency)
  • Heart valve defects and congenital heart disease
  • A blocked artery (arterial occlusion)
  • Decreased blood circulation into your legs (peripheral artery disease)
  • Bulging arteries (aneurysms)
  • Narrowing of an artery, such as in your neck (carotid artery stenosis)

A Doppler ultrasound test may also help your doctor check for injuries to your arteries or to monitor certain treatments to your veins and arteries.
