What is the purpose of ultrasonography?
An ultrasonic scan creates an image of a person's internal body structures using high-frequency sound waves. Ultrasound is often used to examine a developing fetus (unborn baby), abdominal and pelvic organs, muscles and tendons, and the heart and blood vessels of a person.
How do you know if its a boy or girl in ultrasound?
The direction of the nub can be used to determine the baby's sex at the 12 week scan. This is something that can be seen on babies at this age, and if it points vertically, it indicates that the baby is a boy. It's most likely a girl if it points horizontally.
