Functions of 3D and 4D Ultrasounds

With so much advancement in technology, it was inevitable that it became possible to see 3-dimensional and 4-dimensional ultrasound scans of unborn babies. 3D scans show still pictures, whereas 4D scans shows moving 3D images of the baby. 

 

The idea of looking at an ultrasound scan of their baby is a milestone in the lives of new parents, therefore it is understandable how they are usually disappointed with the gray blurry 2D scan that is usually provided. Now however, they are able to see the developing features of their baby, and in 4D they may even be able to witness some movement. It is however important to understand that with the emergence of such technology alongside benefits, there are usually risks involved too. If you plan on getting a 3D or 4D scan purely for souvenir purposes then maybe you should re-think this idea. Since some ultrasound sessions last longer, around 45 minutes, exposing developing babies to that much ultrasound may be well above the recommended safety limits. Once the baby is born, parents will have plenty of time to take pictures and keep as memories but before birth ultrasounds should be kept to the minimum and performed by trained professionals. Studies have been carried out to determine the damaging effects of these ultrasound scans have shown mixed results. But it is entirely possible that negative effects could be established in the future.

These scans are usually not part of the regular prenatal exams, but many practitioners offer these services. Doctors use this invention to closely monitor the development of the fetus and look out for any abnormalities. They can lookout for face defects like cleft lip, or skeletal or neural tube defects. This can help them to prepare for the repair procedures to be taken after birth.

4D scans are recommended on a few occasions such as if the mother is:

1. Experiencing unusual pain
2. Experiencing bleeding or spotting
3. Still unsure of the due date and would like to get a clearer idea of the development of the baby

Another case when pregnant mothers are urged to do these scans are if they have a history of early miscarriage or ectopic pregnancy. These scans will help to monitor if there is any cause for concern and try to neutralize it. 

Furthermore, the equipment required for these ultrasound is costly and not many practices may be able to afford them. Since they are only recommended to be used when there is a dire medical need it is unlikely that these 3D and 4D Ultrasounds will be able to replace the conventional 2D scans in routine checkups.
