A Doppler ultrasound also called a Color Doppler test is a non-invasive test that can be used to estimate your blood flow through blood vessels. It helps doctors evaluate blood flow through major arteries and veins, such as those of the arms, legs, and neck.
Doppler Ultrasound gives doctors a visual or audible representation of blood movement through veins, arteries and blood vessels with sound waves. The reflected sound can be used to diagnose restricted blood flow, blood clots, and fetal health. Unlike ultrasound imaging used to give parents a picture of baby in-utero, Doppler Ultrasound is used to view blood flow to the fetus.
Doppler Ultrasound tests are conducted with a handheld device known as a transducer.
There are three main types of Doppler Ultrasound – Continuous, Duplex and Color.
