If you’re one of the lucky ones who can say, “I’m pregnant!” to anyone who asks, good for you! Congratulations are in order, especially if you have been waiting for your little miracle for a long time. But your excitement and thrill can only be enhanced by having that much-awaited ultrasound, especially if it’s in 3D or even 4D. If you’ve heard about 3D and 4D ultrasounds and are wondering what their difference is with the traditional 2D ultrasound, then this one’s for you. Here’s all you need to know about the main differences between 2D (traditional), 3D, and 4D ultrasounds.

The similarities

While 2D and 3D/4D ultrasounds differ in major ways, there is one similarity among the three: they make use of basically the same technology. This means that they use high-frequency sound waves to create images. The sound waves, as mentioned, are at a very high frequency, so you can’t actually hear anything – the sound wave frequency is well beyond the human ear’s capacity to hear.

The main differences

The main difference between 2D ultrasounds and 3D and 4D ultrasounds is this: with a 2D ultrasound, you only receive an image of your baby in two dimensions. What this means is that the image you see is like that of a normal photograph, with no shadows and no depth. In other words, it’s not as realistic.

With a 3D ultrasound, however, you are presented with an image in three dimensions, giving it depth and shadows and allowing you to see your little one in more precise, realistic detail. It’s a bit like seeing the difference between a 2D cartoon from the 80s and a 3D film (such as Up and Frozen) from the 2000s.

The 3D ultrasound can actually come in different hues or colours, but the golden colour or hue is the one that’s most used because it is said to be the most attractive and aesthetically-pleasing.

What about 4D?

4D ultrasounds are the latest ultrasound innovation you can take advantage of. With 4D, you can actually see your baby move around. It’s still just like 3D, with the only difference that you can see your baby moving – you can see them open or close their eyes, smile, yawn, or suck their thumb. The difference, as you can imagine, is astonishing and amazing.

If you would like to have a 3D or 4D ultrasound of your baby, it would be better to wait until the latter stages of your pregnancy to get a better view and insight. Also, when doing a search for this elective service, it’s better to find a service that’s near you, so to make it easier, search with ‘3D or 4D ultrasound locations near me.’
