What is a Colour Doppler test?
The Colour Doppler test is a diagnostic technique that creates an image from sound waves. It provides information about the speed, movement and direction of blood flow. Your doctors will use this test to check for blockages and clots in your blood vessels. This is not possible with conventional ultrasonography as it fails to show blood flow. In the colour doppler test, no dye is injected into your body. Thus, making this a safe and convenient test. The colour doppler test is based on the Doppler effect. This test measures the sound waves reflected from moving objects like red blood cells to create images of blood flow.
How to understand the test results of the Colour Doppler Test?
The Colour Doppler test uses a computer to convert sound waves into an image. The image will show different colours indicating the direction and flow of blood. These images will be sent to your doctor, who will interpret the result. Irregularities in the images can indicate a blood clot or blockage. Your doctor will use the results of this test to decide on a treatment plan for you.
