A Doppler ultrasound study may be part of an ultrasound examination.

Doppler ultrasound is a special ultrasound technique that evaluates blood flow through a blood vessel, including the body’s major arteries and veins in the abdomen, arms, legs and neck.

A Color Doppler uses a computer to convert Doppler measurements into an array of colours to visualize the speed and direction of blood flow through a blood vessel.
