What Is a Doppler Ultrasound? A Doppler ultrasound is a test that uses high frequency sound waves (ultrasound) to measure the amount of blood flow through your arteries and veins, usually those that supply blood to your arms and legs. Vascular flow studies, also known as blood flow studies, can detect abnormal flow within an artery or blood vessel.
Using Doppler technology, the echocardiogram can assess the speed and direction of blood flow, helping increase the amount and quality of information available from the test. The computer can add color to help the doctor appreciate that information.
