Why should I have a 3D or 4D baby scan?


There are so many reasons behind why people want another glimpse of their baby before it is born. The biggest factors include:

  • Bonding for both mum, dad and perhaps the older brothers or sisters to be
  • To have a beautiful keepsake of such a special time
  • A little sneak peak at what the baby is going to look like before the arrival
  • And sometimes just for peace of mind

What’s in a clear 3D, 4D image?

Ultrasound has been used for decades and has uses on a large scale (sonar for war ships and submarines) to small scale such as looking for small lumps, bumps, tendon tears etc. An ultrasound image is affected by a number of factors and because 3D and 4D imaging uses ultrasound its image quality is subject to the same limitations and then some!

 

  • Placental position can greatly affect our ability to get good views of baby’s face, especially if your baby nestles in to the placenta not giving us the chance for a good clear view
  • Amniotic fluid gives us the ability to take our ultrasound images without the other structures touching the face (such as placenta, uterine wall). Every person and pregnancy is different and so is the amount of amniotic fluid, some people have a lot and some people don’t have much. This factor can’t always be predicted but can affect the overall image quality.
  • Mum’s tum. Now we don’t like to mention it as it doesn’t always make a difference, but sometimes a little bit of belly chub can have an effect as the extra distance the sound waves need to travel to get to your baby and then back to the machine can lead to a image that is less clear Our staff at Sound Radiology are experts in overcoming a number of issues affecting our image quality and we are all professional in the manner we perform our ultrasound scans.
  • Later gestation isn’t always a good time to have the scan as your baby is getting bigger and running out of room! It is that little bit of room around baby that enables us to get the clear images. A lot of people think that the ‘bigger the baby is the better the picture quality’ which isn’t always the case.
  • Experienced staff such as the staff at Sound Radiology ensures that we have the years of experience in ensuring we get the best images possible. We don’t mess with your medical scans to diagnose issues and we have the same expectations when it comes to your 3D and 4D baby images as well.

Can I have a 4D scan after 32 weeks?

Can I have a 4D scan after 32 weeks?


We can certainly perform a 4D scan at this time of your pregnancy but we are aiming to get the best possible pictures for you so we say the optimal window is between 28-32 weeks. We have done quite a few mums at this late stage with great results but things are getting cramped in there as bubs is nearly fully grown which makes it a little more difficult to see the face clearly.

Does the placental position have an impact on the quality of the 4D scan?

Does the placental position have an impact on the quality of the 4D scan?


Having a placenta on the front wall (anterior) can sometimes make it difficult to obtain clear images as the baby likes to snuggle against it, so scanning these babies towards 28 weeks is recommended, as opposed to when there is a back wall placenta (posterior) it is usually ok to scan at anytime in the recommended window period (28 – 32 weeks). At Sound Radiology, you can elect to have your scans at anytime throughout your pregnancy, but it is our job to try and meet your expectations by scanning at certain times to maximize our chances of great images and video footage!
