Color Doppler
A Doppler ultrasound test sees how blood flows through a blood vessel. This technique requires the use of an ultrasound machine which is capable of color Doppler ultrasound.
Uses:
It helps doctors evaluate blood flow through major arteries and veins, such as those of the arms, legs, neck and upper abdomen.
It can show blocked or reduced blood flow through narrowing in the major arteries of the neck that could cause a stroke – CAROTID DOPPLER.
It also can reveal blood clots in leg veins that could break loose and block blood flow to the lungs – DEEP VEIN THROMBOSIS.
VARICOSE VEINS DOPPLER is also done to assess for incompetent perforators and valve competency in order to have targeted therapy.
During pregnancy, a Doppler ultrasound may be used to look at blood flow in an unborn baby (fetus) to check the health of the fetus- PREGNANCY DOPPLER.
Frequently Asked Questions
What is a Color Doppler test used for?
A Color Doppler test is used to evaluate blood flow through arteries and veins in different parts of the body, such as the legs, arms, neck, and abdomen. It helps detect blockages, clots, or narrowing of blood vessels, which may indicate conditions like deep vein thrombosis (DVT), varicose veins, or carotid artery disease.
Is there any preparation required for a Color Doppler scan?
For most Color Doppler tests, no special preparation is needed. However, if the scan is being done for abdominal blood vessels, you may be asked to fast for a few hours before the test to ensure clearer imaging. Your doctor will provide specific instructions if required.
How long does a Color Doppler test take?
The procedure usually takes 15 to 30 minutes, depending on the area being examined. You may need to lie still while the technologist applies gel and moves a transducer over the skin to capture real-time images of blood flow.
Is a Color Doppler test painful?
No, a Color Doppler ultrasound is a completely painless and non-invasive procedure. It uses sound waves to create images and does not involve radiation, making it safe even during pregnancy.
