Ultrasound technology gives you a glimpse of your unborn child and helps doctor detect conditions that could affect your baby's health. Thanks to technological advancements, ultrasounds are now available in 3D and 4D views. The doctors at South Metro OB/GYN in Englewood, CO explain the difference between these two types of ultrasounds.
What are the differences between 3D and 4D technology?
For years, expectant parents showed off grainy 2D images of fetuses to excited family members and friends. Although the scans provide helpful information about your baby's development and growth, they don't provide the sharpest images. With the introduction of 3D images, parents can now view three-dimensional images that look very much like photographs.
3D images are created by capturing a number of 2D images from a variety of angles. When the images are combined, you can see the shape of your baby's nose and chubby cheeks. 4D ultrasounds provide 3D images that capture movement. When you choose a 4D ultrasound, you'll see your baby move his or fingers, yawn, suck a thumb or even open their eyes.
How are 3D and 4D ultrasound performed?
Both 3D and 4D ultrasounds use the same process as 2D ultrasounds. You'll lie on a table with your abdomen exposed. A technician will apply a gel that allows the ultrasound transducer to move easily over your abdomen. The transducer is a device that aims sound waves at your womb. Echos from the sound waves are converted into images of your baby by a computer.
Why are 3D or 4D ultrasounds performed?
Englewood doctors typically rely on 2D ultrasounds to detect developmental issues and birth defects, and evaluate the amniotic fluid, although 3D images can be helpful in identifying some issues, such as cleft lips. 3D and 4D ultrasounds are often used to provide parents with a keepsake of the pregnancy and aren't typically part of regular prenatal care.
