DOPPLER AT BEST CENTERS Of HAUZ-KHAS

What is DOPPLER

Doppler:- Doppler is a test which uses the high-frequency sound waves for measuring the amount of blood flow through your your arteries and veins. It's a pain-less procedure which requires less preparation. A Doppler ultrasound can be used as part of a blood flow study. It is an ultrasound test with noninvasive and you can estimate the flow of blood through your blood vessels by bouncing high-frequency sound waves. A regular ultrasound uses sound waves to produce images, but cannot show blood flow. Doppler ultrasound is suggested by your doctor when your body shows a sign of decreased blood flow in the arteries or veins of your legs, arms, or neck. A decreased amount of blood flow may be due to blockage in the artery, a blood clot inside a blood vessel, or an injury to a blood vessel. This test may also help your doctor to monitor certain treatments to your veins and arteries. Doppler Ultrasound Imaging :

In this method blood flow in the blood vessels is estimated with the help of high frequency sound waves. This method estimates the speed of blood flow. This method is highly useful in diagnosing cardiovascular diseases and conditions like clotting of blood etc. by helping to identify blocked arteries. This Doppler ultrasound imaging has few more terminologies as given below:

Color Doppler :

This uses a wide choice of colors to visualize blood flow measurements embed them within a conventional 2d ultrasound of tissues and structures. This provides a more pronounced representation of blood flow speed and direction than is the case with traditional grayscale images.

Power Doppler :

It provides color imaging of more sensitive and detailed blood flow measurements than regular color Doppler does. This method can sometimes be used to achieve the images in situations which are inaccessible with Color Doppler. However it has a limitation that it can?t detect the direction of blood flow.
