What is a Doppler ultrasound?
A Doppler ultrasound is a noninvasive test (a technique that does not involve puncturing the skin or entering a body cavity) that can be used to evaluate the blood flow through your blood vessels by thriving high-frequency sound waves (ultrasound) off circulating red blood cells. A systematic ultrasound uses sound waves to fabricate images, but cannot show blood flow. The amount of blood flow through your and veins and arteries, normally those that provide blood to your arms and legs, is measured by the high-frequency sound waves. Blood flow studies, also known as, vascular flow studies, can diagnose abnormal flow within a blood vessel or an artery.
Numerous disorders may be detected with the help of a Doppler ultrasound, including:
Venous insufficiency-Poorly performing valves in your leg veins, which can cause blood or other fluids to puddle in your legs
Congenital heart disease and Heart valve defects
Arterial occlusion-A blocked artery
Peripheral artery disease- Reduced blood circulation into your legs
Carotid artery stenosis-Narrowing of an artery, such as in your neck
A Doppler ultrasound can detect how fast blood flows by measuring the rate of change in its pitch or frequency. During a Doppler ultrasound, a sonographer or a technician trained in ultrasound imaging presses a transducer which is a small hand-held device, approximately the size of a slab of soap, against your skin over the area of your body being investigated, moving from one area to another as needed.
This test may be done as a substitute to more-aggressive procedures, such as angiography, which requires injecting dye into the blood vessels so that they show up evidently on X-ray images.
The 3 basic kinds of Doppler ultrasound are:
"Bedside" or continuous wave Doppler
A Doppler ultrasound test may also assist your doctor examine injuries to your arteries or to detect definite treatments to your arteries and veins.
