That’s why we adhere to a principle while performing ultrasounds called ALARA: as low as reasonably achievable. Under some circumstances, heat can lead to birth defects. The ultrasound waves used to image the baby expose the baby to energy in the form of heat. While doctors and sonographers may be able to easily recognize it in a 2-D image, parents are often able to better visualize the abnormality in a 3-D image. They also are helpful when we need to explain an abnormality to parents. However, 3-D and 4-D ultrasounds can be important tools to assess some abnormalities that are hard to look at in 2-D, such as cleft lip. While 3-D can give a nice picture of the outside of your baby, 2-D ultrasound is really the standard that has been developed by experts to look for abnormalities in development and growth of your baby. We usually don’t need 3-D to assess how your baby is developing. So why don’t we use 3-D all the time if we have the capability to do so? Simply, 2-D often is more efficient. This looks more like what you’re used to seeing in a typical photograph.Ĥ-D is similar to 3-D, but it shows movement, so you can see your baby kicking or opening and closing their eyes. In a 3-D ultrasound, many 2-D images are taken from various angles and pieced together to form a three-dimensional image.
2-D, 3-D, and 4-D ultrasounds: What’s the difference?Īll ultrasounds use sound waves to create an image of your baby in the womb:Ī regular 2-D ultrasound creates a cross-sectional view of your baby. Let’s talk about why and when doctors use them, and I’ll share my concerns about having a 3-D or 4-D ultrasound in a non-medical setting. But it’s important to remember that an ultrasound is not just for entertainment. Medical groups such as the American Congress of Obstetricians and Gynecologists (ACOG) also discourage the use of commercial ultrasounds. This is despite the fact that the Food and Drug Administration (FDA) warns parents to avoid them. More expecting parents than ever are paying to get photos and videos of their babies that are more lifelike than the 2-D ultrasounds from their doctor’s offices. A quick Google search reveals that nearly a dozen businesses in the Dallas-Fort Worth area offer 3-D and 4-D keepsake ultrasound services.
