There are generally two types of ultrasounds that are used during pregnancy to screen for genetic conditions and birth defects: the first trimester ultrasound, and the anatomy ultrasound. Their recommendation is that ultrasounds be performed only for medical reasons by qualified health care providers. However, according to the American College of Obstetricians and Gynecologists patient information on ultrasound, it is possible that harmful effects could be identified down the road. For example, there have been no associations between ultrasound and birth defects, childhood cancer, or developmental delays later on in life. However, some women may have an earlier ultrasound or more ultrasounds if they have bleeding, pain, or other concerns are identified on an initial ultrasound.Ĭurrently, there is no reliable evidence that ultrasound is harmful to a developing baby. It is fairly common to have at least one ultrasound during pregnancy. Ultrasound can also be used to screen for birth defects, such as spina bifida, heart defects, and cleft lip. This picture can be used to take measurements, which can be used to verify how far along a pregnancy is and to monitor growth throughout the pregnancy.

Ultrasound involves using sound waves that reflect off of the different parts of the baby to generate a picture.

Prenatal ultrasound, also known as sonogram, is an imaging technique that is used to look at a fetus during the pregnancy.
