A Doppler ultrasound test uses reflected sound waves to see how blood flows through a blood vessel. It helps evaluate blood flow through major arteries and veins, such as those of the arms, legs, and neck. It can show blocked or reduced flow of blood through narrow areas in the major arteries of the neck that could cause a stroke.
