What is USG Level II (18 - 22 Weeks)?
Ultrasound imaging also called as sonography uses a transducer or probe to generate sound waves and produce pictures of the body's internal structures. It is often used to help diagnose unexplained pain, swelling or infection. It is used to see internal body structures such as tendons, muscles, joints, vessels and internal organs. It may also be used to provide imaging guidance to needle biopsies or to see and evaluate conditions related to blood flow. It is also the preferred imaging method for monitoring a pregnant woman and her unborn child. It does not use ionizing radiation, has no known harmful effects, and provides a clear picture of soft tissues that don't show up well on x-ray images.

A Doppler ultrasound study – a technique that evaluates blood flow in the umbilical cord, fetus or placenta – may be part of this exam. It is a totally painless and safe procedure. It is useful test to establish the presence of fetus, estimate the age of pregnancy, diagnose congenital abnormalities of the fetus, assess fetal growth and well being etc.
