The anatomy scan is an ultrasound that is done approximately 20 weeks into your pregnancy. This scan is designed to tell doctors many different things about the developing baby. It is a level two ultrasound that many mommies-to-be get excited about because it will reveal the gender of the baby. However, this ultrasound provides other vital information about the development of the baby. The technician will be able to examine the heart, face, spine, brain, and other organs to help evaluate for any birth defects.
