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. 

Our doppler products 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)

Our Doople Ultrasound can estimate how fast blood flows by measuring the rate of change in its pitch (frequency). 

This test may be done as an alternative to more invasive procedures, such as angiography, which involves injecting dye into the blood vessels so that they show up clearly on X-RAY images.
