By now, you’ve probably heard someone mention having a 3D ultrasound at somepoint. Whether it’s yourself, a coworker, family member, or just someone in passing – everyone seems to be talking about it. But what exactly is a 3D ultrasound?
A 3D ultrasound show still pictures of your baby in three dimensions. 4D scans show moving 3D images of your baby, with time being the fourth dimension.
It’s natural to be really excited by the prospect of your first ultrasound. But some moms find the standard 2D scans disappointing when all they see is a grey, blurry outline. This is because the scan sees right through your baby, so the photos show her internal organs.
With a 3D ultrasound, you see your baby’s skin rather than her insides. You may see the shape of your baby’s mouth and nose, or be able to spot her yawning or sticking her tongue out.
Is a 3D Ultrasound safe?
A 3D ultrasound is considered as safe as regular 2D scans, because the images are made up of sections of two-dimensional images converted into a picture. However, experts do not recommend having 3D or 4D scans purely for a souvenir photo or recording, because it means that you are exposing your baby to more ultrasound than is medically necessary. Some private ultrasounds can be as long as 45 minutes to an hour, which may be longer than recommended safety limits.
3D and 4D scans may nonetheless provide more information about a known abnormality. Because these scans can show more detail from different angles, they can help in the diagnosis of cleft lip. This can help doctors to plan the repair after birth.
3D scanning can also be useful to look at the heart and other internal organs. As a result, they are often used during anatomy scans or if there is suspicion of an abnormality.
There’s no evidence to suggest that the scans aren’t safe, and most moms-to-be gain reassurance from them. Nonetheless, any type of ultrasound scan should only be performed by a trained professional, for as short a time and at the lowest intensity, as possible.
When is the best time to preform a 3D Ultrasound?
If you decide to have one, the best time to have a 3D or 4D scan is when you’re between 26 and 30 weeks pregnant.
Before 26 weeks your baby has very little fat under her skin, so the bones of her face will show through. After 30 weeks, you baby may begin to move further down – making the visibility of her face to become more difficult.
It is important to not that you may not always be able to see your baby’s face during a 3D Ultrasound. Placement of your placenta, the way the baby is facing, how far down she is, and how far along you are all factor in to the clarity of the scan.
