What is Sonography Doppler?
Doppler sonography or Doppler ultrasound is a medical imaging technique that uses ultrasound improved by a doppler effect. The Doppler effect generally uses a change in sound wave pitch, which are measured by ultrasound -receiving devices such as the converter. Color Doppler images often provide useful information about blood flow and movement and inner areas of the body. This technique is commonly used during pregnancy to provide detailed images of the developing unborn child. Further use of Doppler Sonography may include visual tests of tendons, joints and muscles, as well as internal organs. This test usually shows the size of the developing fetus and can provide information about the health of the fetus, such as the amount of oxygen received. Doctors can identify health conditions in some pregnant mothers such as anemia of sickle cells or preeclampsia, with the help of this test.
Some doctors have patients subject to Doppler sonography to explore a number of health conditions. Patients with leg pain may have intermittent claudication and atherosclerosis, which in some cases may occur in Doppler's sonographic image. With this form of ultrasound, varicose veins and other abnormalities of blood vessels can be examined. In some cases, blood clots and blood flow blocking can be identified. Some doctors use this form of ultrasound to provide images that control their work during surgery, such as ablation of blood vessels.
The patient usually lies on his back or side during ultrasound. Medical experts usually apply a special doppler gel to the skin near the area where pictures are required. The converter is typically opposed the gel skin and moved around to get Doppler's sonographic images from several desired angles. Most doppler ultrasonic tests are completed in 30 to 60 minutes. DoctorsIn recommended that patients do not wear jewelry during the test to reduce the chances of distortion of the image.
In some cases, patients have unreliable results from Doppler Sonography due to several factors. Patients who do not stay during the procedure may cause images to record images. In some cases, the bones in the body may block ultrasonic signals used during the test. Reliable ultrasonic images may be more difficult to obtain in obese individuals and irregular heart rhythms can cause unusual images of blood vessels.
