a doppler ultrasound is a test that is done to see the flow of blood through blood vessels. it is an imaging test and uses sound waves to create images of the moving parts such as red blood cells. it is similar to the normal ultrasound because both use sound waves to create images. the only difference is that the normal ultrasound can only be used to see the images of the organs and it cannot be used to show the images of blood flow.
dopplers are used by doctors to find out if there is any condition that is reducing or blocking the flow of blood in your body. it is used for diagnosing heart diseases. it is also useful for checking the functioning of the heart. it helps to look for any blockages in the blood flow in the legs thus causing deep vein thrombosis. it also helps in determining the narrowing of the blood vessels. narrowing of arteries in the legs means that you are suffering from a condition called peripheral arterial disease and if there is a narrowing of arteries of the neck it means that you have a condition called carotid artery disease.
