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.
