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.
As an alternative to more invasive treatments like angiography, which involves injecting dye into the blood arteries to make them visible on X-ray pictures, this test may be performed.
Your doctor may use a Doppler ultrasound to assess for artery damage or to keep track of specific vein and artery therapies.
