About Doppler Ultrasound: A to Z You May Want to Know

A Doppler ultrasound is an imaging test. This test uses sound waves to show movement of blood through blood vessels. To create images of structures inside the body, sound waves are being used by regular ultrasound procedures as well. A regular ultrasound however can’t show blood flow.

Doppler ultrasound works by measuring sound waves. It measures the sound waves which are being reflected from moving objects like red blood cells and the phenomenon is called the Doppler effect.

There are different types of Doppler ultrasound tests. These are as below:

• Color Doppler – A color doppler uses a computer to change sound waves into different colors. These colors help in showing the speed and direction of blood flow in real time.
• Power Doppler – This is a newer type of color Doppler. More detail of blood flow can be provided by a power doppler than standard color Doppler. The disadvantage of a power doppler is that it cannot show the direction of blood flow. The direction can be important in certain medical cases.
• Spectral Doppler – A spectral doppler test shows blood flow information on a graph, rather than on color pictures. It can help in showing how much of a blood vessel is blocked.
• Duplex Doppler – A duplex doppler uses standard ultrasound. This test takes images of blood vessels and organs. These images are then turned into a graph by the computer.
• Continuous wave Doppler. Sound waves are sent and received continuously in a continuous wave doppler test. It allows for more accurate measurement of blood flowing at faster speeds.

An echo doppler test in Kolkata is performed at all major diagnostic centres and hospitals. An echo doppler test cost in Kolkata is normally Rs. 1500 to Rs. 1600 and an echo color doppler test cost in Kolkata is around Rs. 2000.

What is a Doppler Test used for?

Doppler ultrasound tests are used to help your doctors find out if you are having  a particular health condition. It is used to assess a condition that reduces your blood flow or is blocking your blood flow.

It may also be used to help in the diagnosis of certain heart diseases. A doppler test is used for the following functions:

• Check heart function – This process is often done along with an electrocardiogram. Electrogram is a test that measures the electrical signals in the heart.
• Look for blockages in blood flow – Blocked blood flow in the legs can lead to a serious health condition known as deep vein thrombosis or DVT.
• Check for blood vessel damage

• Check for defects in the structure of the heart.
• Look for narrowing of blood vessels. Narrowed arteries in arms and legs can indicate a health condition called peripheral arterial disease or PAD. Narrowing of arteries in the neck can be due to a condition called carotid artery stenosis.
• Monitor blood flow after surgery.
• Check for normal blood flow in a pregnant woman and the developing fetus.
