Ultrasound
Ultrasound imaging (also called Sonography) is safe, simple and painless method of obtaining diagnostic images from inside the human body through the use of high-frequency sound waves. There is no radiation exposure associated with ultrasound diagnostics and there are no injections.
These scans are also able to capture moving images of abdominal function (including gallstones), the male reproductive system, breast abnormalities, thyroid systems and the kidneys. When combined with a special technique, ultrasound can also capture moving blood images of large blood vessels.
