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.
The patient may be asked to perform some exercise before the test in order to increase the heart rate, or they may be administered with medicine that increase the heart rate. A doppler echocardiogram is performed to examine the blood flow in the heart, by measuring the speed and direction of the blood flow. This test is usually performed as a part of the TTE and TEE test.
