Best Features And Uses Of Sonography
Sonography is mainly done for the evolution of the precious aspects of human, fetus. This cannot be replaced by any other modality and the sonography is the primary base line of evaluation in the abdominal disorder and also disorders of other organs.
The three basic classification of Sonography are interventional Sonography, routine Sonography and color and dopper Doppler. This modality is based on the frequency of 20 KHZ of the ultra sound. The high frequency sound waves will travel forward until it touch the targeted object. After the contact with object some sound is bounced back. The frequency of ultra sound is 1 to 15 MHZ is beamed in to human body in medical practice and it is detected by the echoes returned. The sonographer will place the scan head transducer on the area it needs to be scanned. In order to ensure the air free path the aqueous gel is applied on the scanning area. To do the examination the transducer is moved over the scanning area of the body. The ultrasound penetrates and strikes the organ and it will reflect back on the surface of body. Then, the sound waves that are returned by the transducer are detected. The echoes are processed by the computer in two dimensional images that appear on screen. This image is called as sonogram.
The Sonography is painless and it is non invasive. It is safer than the radiography because there are no radiation exposures. It is very comfortable and less expensive. The foetal growth is assessed with the help of Sonography . The abnormalities like the spinal bifida can be detected with Sonography. Sonography helps to diagnose the problems like oviducts, kidney stones, gall stones, obstruction in uterus and intestine. Sonography also helps to measure blood flow through heart, arteries, veins based on Doppler Effect phenomenon.
With the help of Sonography you can know the baby condition and also the development of the baby. With Sonography you can also detect the injuries, jaundice, breast disease, thyroid, valve defects, tumor, TB and many other disease.
The interventional Sonography is used for detecting tumor biopsy, abnormalities in the chromosome of fetus, abnormal fluid collection and many more. With the help of the dopper and color Doppler Sonography you can deter the organ functions. The main purpose of using this sonography is to study the growth of baby in uterus, function of heart, blood flow evaluation, to detect any defects in heart, to detect if the tumor is cancer or not.
