3D & 4D Pregnancy Ultrasound


What are 4D and 4D Scans?

3-D scans are still pictures of the baby in three dimensions, whereas 4-D scans are moving 3-D images of the baby.  The images show the outside of the baby rather than the more familiar 2D images which show an outline of the baby with the internal organs visible.


When can I have a 4d Scan performed?

The best time to have a 3-D or 4-D scan is between 26 and 30 weeks. Before 26 weeks your baby has very little fat under her skin, so the bones of the face show through the skin. After 30 weeks her head may go deep down in your pelvis, so you might not be able to see her face.


Are 3D or 4D Scans superior to 2D scans?

From a medical point of view the benefits of 3-D and 4-D scans appear to be limited. Occasionally they can be useful in giving additional information about a known abnormality.  As there are few clear medical benefits it's unlikely that these scans will replace normal 2-D scans in the near future. 


There is some evidence to suggest that this type of scanning assists the bonding process between mother and baby.


Are 4D Scans harmful to mother or baby?

These scans use exactly the same technology as traditional 2D ultrasound scans but rather than taking a single image, they comprise multiple images processed very quickly in a powerful computer to create the 3D image.


Accordingly, they are just as safe as normal 2D scans, which have been used in pregnancy for nearly 30 years and there is no evidence to suggest they cause harm to either mother or baby.
