Common Uses Of Vascular Doppler

A specific application of vascular ultrasound is the Vascular Doppler. Not unlike the underwater sonars used to detect large vessels like submarines, ultrasound imaging or scanning in the medical industry then again is more defined. The type used for examining the body is sonography, and is well known to many people. Pregnant women notably are familiar with this technology, in order to examine the growing baby in utero.

Because it is harmless and painless, ultrasounds are utilized for a variety of reasons. A replacement for x-rays, ultrasounds are a lot safer. With an ultrasound there is absolutely no exposure to radiation. Using a small transducer, an ultrasound examination converts sound waves to electrical impulses to form the impression. The sound waves produced by the transducer or probe are transmitted through the entire body with a special ultrasound gel.

Specifically, vascular ultrasound provides illustrations of the veins and arteries within the body. When blood flows in the blood vessels, the reflected frequency of the sound waves alters a little, in proportion to the speed. This is known as the Doppler effect. This is utilized to yield a special type of ultrasound procedure called vascular Doppler. With this procedure, the blood flow is monitored and diagnosed too.

The final results of this examination can be displayed in three ways. You will find a Spectral Doppler, the Color Doppler and also the Power Doppler, which are the three available methods. The measurements are changed into a color chart when using the Color Doppler. Just like the modern GPS system that tracks traffic movement, the flow of blood is mapped indicating if there is an impediment or other problems. The veins and arteries are normally represented using colors for instance yellow and red. For flow in the opposite direction, the cool colors are used, perhaps violet for a fast flow, and green for a slower movement.

A more recent method that displays the blood flow more effectively and vividly is the Power Doppler. Unfortunately, like the other two ways of imaging blood flow, the output of Power Doppler offers no indication of direction. Spectral Doppler will not display the final results visually. A graph is generated where the distance traveled is viewable per unit time.

The Vascular Doppler has lots of functions. Blood is monitored as to the way it flows through tissues or organs where this analysis is helpful for various procedures. It can recognize and locate a stenosis or blockages as well as other problems for example plaque or emboli. It can also detect blood clots, and deep venous thrombosis (DVT) in the major veins in the arms and legs of the body. Other uses include assessing the success of grafting blood vessels, determining the degree of varicose veins, oversized arteries or aneurysm and in establishing if particular procedures are necessary including angioplasty.

Because of its non-intrusive character, this imaging approach is particularly useful for proper diagnosis of children and infants. It is not easy at times to position a needle or catheter in a vein or artery in certain circumstances. The Doppler measurements help perform this procedure effectively. If a child has a congenital vascular malformation in the form of an arteriovenous malformation or a fistula, Doppler measurements can measure the salient artery or vein connection. It is likewise beneficial during a dialysis fistula.

In the medical field, there continues to be more discoveries being made for this innovative type of imaging.
