Ultrasound is a procedure that uses high-frequency sound waves to view internal organs to produce images of the human body.
It is noninvasive, which means it does not penetrate the skin or body openings, and Diagnostic, which means it is used to determine what disease or condition is present. The technical term for ultrasound imaging is sonography.
One of the most common uses for ultrasound is to view the uterus and fetus during pregnancy.
Ultrasound is a very safe and painless procedure so there is little risk.
