![]() ![]() This is usually the ultrasound where the gender of the baby can be determined. During this screening test, the doctor will also look at important organs, such as the heart, the brain, and the kidneys. The fetus is checked out from head to toe, and measurements are taken of its head, limbs, and abdomen. The anatomy (or level 2) ultrasound, usually done around 20 weeks, is where a lot of measurements are taken. If the NT measurement is larger than expected, it can increase the risk for chromosome conditions, such as Down syndrome, as well as heart defectsĪ normal first trimester ultrasound does not guarantee a healthy baby, but it does lower the chance for certain birth defects and genetic conditions.It can measure a pocket of fluid behind the fetus’ neck called the nuchal translucency (NT).It can see if there is more than one fetus (twins, triplets, etc).It can estimate how far along the pregnancy is.It can verify the presence of a viable pregnancy.Although the fetus is still very little, there are some important things that this ultrasound can tell us: ![]() The first trimester ultrasound is usually done in the first trimester (from conception up until about 14 weeks), and the baby is small at this time, only a few inches in length. 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. ![]()
