What is Doppler's ultrasonography?
Doppler's ultrasonography, also known as the ultrasound doppler, is a imaging technique that provides visualization of blood flow through arteries. It is a non -invasive and painless procedure that uses sound waves to diagnose the disease. The procedure can be performed as a possibility of X -ray imaging techniques such as venography and arteriography that requires dyeing dye into the blood vessel to make it clearly visible to the X -ray. Doppler's ultrasonography can help, among other things, to see blood clots, aneurysm and heart valve problems. It can be carried out in large veins and arteries of the body such as legs, neck and arms.
There are basically three forms of Doppler ultrasonography: color, strength and spectral. With the help of a computer, Color Doppler Doppler metrics into a range of colors to provide a picture of the direction and blood flow through the artery. Power Doppler, can provide more information about blood flow, especially in situations where only blood flow; Usually usedwhen evaluating blood flow by arteries located in solid organs. The spectral doppler displays details of blood flow in the graph rather than in the form of an image.
Doppler ultrasonography uses two complementary principles - ultrasound and doppler. Ultrasound is based on the principle that the high -frequency sound bounced back from its destination to where it came from. Doppler's principle, on the other hand, claims that the sound of the sound increases when the sound source is close to listening to it; On the contrary, the sound spacing decreases when the sound source moves from the listener. The use of these two principles leads to the creation of an image of the examined body using Doppler's ultrasonography.
technician, known as a sonograph, performs Doppler's ultrasonography. It uses a handwritten, also known as a probe. Press the converter on the skin of the person in the area where the organ inspection is located. Gel is often applied to the skin area to be a sonoVana for easier movement of the converter. The image of the organ is captured at various angles in the X -ray, disk or paper for use for Doctor Who for Doppler's ultrasonography.
No preparation is required before the Doppler ultrasonography is required. This can be done as an outpatient procedure and does not require care for the procedure.
