Colour Doppler

Color Doppler is a method of visually detecting motion or blood flow using a color map that is incorporated into a standard B-mode image.The significance of Doppler ultrasound in evaluating pregnancies that have the risk for preeclampsia, intrauterine growth restriction, fetal anaemia, and umbilical cord abnormalities has become indispensable. Recent findings aided in timing delivery of severely growth-restricted fetuses by promoting the use of ductus venosus Doppler. Primarily it appeared that abnormalities in ductus venosus waveform were the endpoint for pregnancies distressed with intrauterine growth restriction contrary to newer data proposing these abnormalities as plateau prior to further fetal deterioration as observed by changes in the biophysical profile.



What is Colour Doppler test?

Color Doppler is a technique in which colors superimposed on an image of a blood vessel indicate the speed and direction of blood flow in the vessel. Colour doppler test is a type of ultrasound test.
Doppler ultrasound tests are used to help health care providers find out if you have a condition that is reducing or blocking your blood flow. It may also be used to help diagnose certain heart diseases. The test is most often used to: Check heart function.
A Doppler ultrasound is a noninvasive, painless procedure that doesn't expose you to harmful radiation. There are no risks associated with this test, and most people feel little to no discomfort during the procedure.
