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.
Contrast echocardiogramâA solution is injected into the vein and can be seen in the heart. Stress echocardiogramâThis records the heart's activity during a cardiac stress test. Echocardiogram with Doppler ultrasoundâThis helps your doctor assess blood flow. Transesophageal echocardiogramâTo provide clear images of the heart, the ultrasound device is put down your throat.
