What is a color Doppler?
A Color Doppler is a form of ultrasonography test called a "Color Doppler" that shows the speed and direction of blood flow in a blood artery by superimposing different colors on an image of the bloodstream.
This particular ultrasound test uses a computer to transform sound waves into different colors. These hues represent the blood flow's velocity and direction in real time.
Compared to a regular color Doppler exam, a new type of color Doppler test called Power Doppler helps provide more precise information about blood flow.
Your doctor may use a Doppler ultrasound to assess for artery damage or to keep track of specific vein and artery therapies.
Other names: Other name of this test is Doppler ultrasonography
