Cardiology Associates of South Florida may recommend a Doppler ultrasound if you have signs of decreased blood flow in the arteries or veins of your legs, arms, or neck. Reduced blood flow can be due to a blockage in an artery, a blood clot inside a blood vessel, or damage to a blood vessel.
A Lower Extremity Arterial Doppler test provides your doctor with important information about blood flow through the major arteries and veins. It can also show how much blood flows in the arteries and veins.
A Doppler ultrasound is a test that uses high-frequency sound waves to measure the amount of blood passing through arteries and veins, usually those that supply blood to the arms and legs.
There are several types of ultrasound, but arterial Doppler ultrasound may be more helpful in diagnosing lower extremity peripheral arterial disease. Radiologists can hear sound waves bouncing off red blood cells to determine the speed of blood flow in the arterial area. Vascular ultrasound is a non-invasive method of examining blood circulation.
