Like regular ultrasounds, 3D and 4D ultrasounds use sound waves to create an image of your baby in your womb. The difference is that 3D ultrasounds create a three dimensional image of your baby, while 4D ultrasounds create a live video effect, like a movie where you can watch your baby smile or yawn.
Parents often want 3D and 4D ultrasounds, because they let you see your baby’s face for the first time. They also show certain birth defects, such as cleft palate that might not show up on a standard ultrasound. Studies suggest that 3D and 4D ultrasounds are safe. Plus, the images can help doctors spot a problem with your baby and make it easier for them to explain it to you.
The ultrasound is done by abdominal ultrasound. You’ll lie down and a technician will put a special gel on your belly. This helps carry the sound waves. Then the technician will hold a probe against your belly and move it around to get an image. Afterward, you may get photos or a copy of a 4D movie to take home.
But keep in mind that these ultrasounds are not typically used to diagnose problems with your baby. Also, getting a 3D ultrasound at a commercial center or someone’s home based business, is not a substitute for medical care. It may be best to look for a 3D ultrasound company that is located in a medical building. Due to access to other medical professional, such as OBGYN, Family doctors etc. and most importantly, it is maintained and designed as per the medical standard guideline.
