Question: What is a 4D pregnancy scan?

3D scans show still pictures of your baby in three dimensions. 4D scans show moving 3D images of your baby, with time being the fourth dimension.

What is the purpose of a 4D ultrasound?

Is 4D scan safe for baby?

Does 4D scanning present any risk to the baby? No. 4D scans are no different to conventional 2D scanning in that they use sound waves to look inside the body. The images are collected by the ultrasound machine and then processed by the computer to give a three dimensional image.

When do you have a 4D scan when pregnant?

How far along should I be before I have a 4D ultrasound? If you plan on having only one 4D ultrasound session, we would recommend having the ultrasound performed between the 26th and 34th week of the pregnancy.

What happens at a 4D ultrasound?

4D ultrasounds: A 4D ultrasound is similar to a 3D ultrasound, but the image shows movement like a video would. So in a 4D sonogram, youd see your baby doing things in real time (like opening and closing his eyes and sucking his thumb).

Can a 4D scan detect abnormalities?
