One of the most rewarding moments for expectant parents is when they get to see their child for the first time on ultrasound. Many people choose to do this before the routine examination in the public sector. It is not always easy to know what is what when ordering an ultrasound. Here we explain what ultrasound is, and the difference between 2D, 3D and 5D ultrasound. In a future post, we will write more about what you can see in the different weeks of pregnancy.

What are (2D, 3D, 4D and 5D) ultrasound?

Ultrasounds are sound waves that have a frequency that is higher than what humans can hear (high frequency sound waves). When the sound waves are sent from the sound head (probe), the sound wave meets tissue in the body. The tissue sends back a kind of echo. Different types of tissues in the body, send back different echoes. The echo is sent back to the sound head, and the ultrasound machine converts the sound waves into ultrasound images.

Is ultrasound dangerous?

No, sound waves are not known to cause side effects. Ultrasound is not the same as X-ray, and therefore has no radiation risk. Long-term studies show that there is no risk that it affects the growth, language or physical development of the fetus.

What is the difference between 2D, 3D, 4D and 5D ultrasound?

2D ultrasound is the most “known” ultrasound. These images provide “flat” images. This is the type of ultrasound you usually take until week 24. After week 24, it may also be relevant with 3D ultrasound for those who want it. All medical measurements are made in 2D regardless of the week of pregnancy. In 2D you see the skeletal structure that makes internal organs visible.

3D ultrasound is the more classic cozy pictures expectant parents want. The pictures are three-dimensional and can show the baby’s facial features and body shapes. The nicest pictures are around week 26-27. This is because the baby has gained a little more subcutaneous fat, and looks a little rounder and fuller.

4D ultrasound is several 3D images in a row, in other words a video! 3D in video can capture the baby’s movements in the form of e.g. facial expressions, smiling, yawning or kicking. It becomes like a small window into the little one’s belly in real time.

There is also 5D ultrasound. These are HD images, also known as HD live. There is no noticeable difference for the untrained eye. 5D images are similar to 3D images, but the baby’s skin appears in a more pinkish tone.
