Doppler Ultrasound ImageMother who visit the Hospital and have requisition letter from her Doctor to do Doppler Ultrasound. She will ask me “What is Doppler Ultrasound?”.

Some of them are very familiar with ultrasound test due to pregnancy ultrasound, but others are also still confuse what Doppler ultrasound for. Ultrasound in term is the sound waves of frequencies exceeding the range of human hearing. Doppler it self is a little bit innovations in clinical practice.

The power of Doppler Ultrasound is better agents for anatomy, measurement of tissue perfusion and precise delivery mechanism of soft tissue in color images.

Doppler Ultrasound is based on the shift of frequency in ultrasound wave caused by a moving reflector. Compared with conventional ultrasound, Doppler test is rather complicated and more accurate for detecting any abnormalities. The power Doppler produces images that have more sensitivity to motion and are not affected by the Doppler angle. Greater sensitivity allows detection and interpretation of very subtle and slow blood flow.

The moving reflector in the body are the blood cells. The Doppler technique can be used to create color blood flow maps of the vasculature. The sound waves and the blood cells must move in parallel directions.

Doppler ultrasound is not only used for pregnancy examination but also for any other tests like thyroid glands, hands, legs, abdomen, testicles, etc. Of course the price is higher than the conventional ultrasound.

Nowadays, Doppler techniques are becoming more common in the clinics or hospitals and to be medical standard of ultrasound equipment. Several tests can be performed including in maximum penetration depth, accuracy of velocity measurements and volume flow.

So, Color Doppler Ultrasound can useful for diagnostic tool of many abnormalities related with blood flow, artery, vein, blood vessel, soft tissue, stenosis, cyst, thrombosis, rupture, etc.

If you have disease related with the above mentioned, Please consider to use Color Doppler Ultrasound.
