Many parents look forward to catching a glimpse of their little one during pregnancy. Knowing your baby is growing and developing in your belly, even feeling little flutters and movements, makes 9 months a long time to wait to kiss those little fingers and toes! Ultrasounds allow you to see your developing little one, and they also can be a helpful diagnostic tool for your care provider. There are so many choices today – how do you know if a 2D, 3D or 4D ultrasound is best? We asked one of our Kiinde expert partners, Baby Face HD Ultrasound, to share all about 3D and 4D ultrasound technology.

What is the difference between a 2D or 3D, 4D ultrasound?

“New parents have a big choice to make when it comes to ultrasounds:
should we get a 2D or 4D ultrasound? Parents have more options than ever before when it comes to seeing their future child. 4D ultrasounds are one such option. Unlike a 3D ultrasound, a 4D ultrasound shows a fourth dimension: time. This technology kicks it up a notch by leveraging the power of specialized computer programming to deliver a crisper, clearer, and life-like image of the baby. What does that mean? With a 3D ultrasound, you see a 3-dimensional image of your child in your womb. With a 4D ultrasound, you see those 3D images moving. It’s a live stream of the fetus.”

Ultrasound Imaging: What's the difference. 2D and 3D/4D ultrasound

First, let’s do a basic overview of the differences between the three
types of ultrasounds.

“2D ultrasounds: show a grey, blurry outline of your baby. With a
traditional 2D ultrasound, the scan sees right through your body. That
means a 2D ultrasound is essentially revealing your baby’s internal

With 3D and 4D ultrasounds, you see more than just your baby’s internal
organs: you see his or her skin. You can see the shape of your baby’s
mouth and nose. You can see if your baby is yawning, sucking his or her
thumb, or sticking his/her tongue out. You get a more realistic look at
your future child.

The main advantage of a 4D ultrasound is that you can see a moving image
of your child. Again, time is the fourth dimension here.”

Are 3D/4D Ultrasounds Safe During Pregnancy?

“The revolutionary ultrasound technology is safe. 2D, 3D, and 4D
ultrasounds are safe. The reason is simple: 3D ultrasounds are just a
collection of two-dimensional images converted into a picture by
computer software. A 4D ultrasound provides the best-quality visual of
your baby and can also make for a better memento. Many parents prefer a
video of the fetus over a photograph.”


Why would you have a 3d ultrasound?

“3D/4D ultrasounds offer parents a chance to create a bond with their
child before birth. It can spruce up the communication and strengthen
the relationship between parents. It’s a super cute keepsake of the
pregnancy. It helps reassure the parents that the baby is healthy and
growing and helps older siblings feel connected and prepare for the
soon-to-be new member.”

Ultrasounds are part of your prenatal care

These 3D/4D ultrasounds are elective procedures. A diagnostic ultrasound will be done by your prenatal care provider as needed during your pregnancy. Some of the reasons your provider might do an ultrasound during your pregnancy:


To determine the gestational age of your baby or to confirm your estimated due date 

Confirm the number of babies you are carrying

Watch and listen to your baby’s heartbeat 

Check anatomy and determine the sex of your baby

Measure baby’s developing organs 

Check your amniotic fluid levels 

Estimate the size of your baby 

Determine the positioning of your baby

Check for certain birth defects and anomalies 

To reassure parents that baby is healthy and all is going well in their pregnancy 



Please remember to consult with your prenatal care provider before receiving any type of elective procedure. While these ultrasounds may be safe during pregnancy, your doctor will know your unique situation and needs best.
