3D/4D Scan

It's a great experience to see your unborn child in three dimensions.

         
You can really get a good impression of how the baby looks. Almost like a photograph..

D4D scanning means that you see the baby moving over time in 3D.

We alternate between 3D and 4D during the ultrasound depending on that the baby is doing. In this examination we can see the baby's arms, legs and face. if we are lucky the baby may smile or suck its thumb. When the baby's face is turned away we can get some great recordings of it's hands and feet. It's a wonderful experience to see the baby, even if you can't see the whole baby at one time.


What does my scan include?

We record the entire ultrasound onto a DVD. All the pictures we print out on the machine during the scan are also on a DVD as jpeg files. You can easily see both DVDs on your computer and e-mail the jpeg files to friends and family.

You can also use the jpeg files to create a small photo book with the very first baby 'photos'. So you get 2 DVDs when having a 3D/4D ultrasound.

 

We calculate the baby's size and weight.

To do that we measure the width and length of the head, the abdomen and the femur. A computer then calculates the baby's weight and compares it to the average size of a foetus that age.

We use the same measuring methods as the hospitals and the calculation is done using the software ASTRAIA which is also what the hospitals use. You can therefore compare your results with scans earlier in your pregnancy and see how the baby gains weight.

We also measure the flow rate in the umbilical chord. That determines if the baby is getting enough nutrients and it also means that you will be able to hear the baby's heart beat during this examination. We evaluate the amount of amnion fluid and determine where the placenta is located.

If you want to know the sex of the baby, we can also see that.

 

Any questions you may have about your pregnancy are very welcome, so feel free to ask the doctor anything during your ultrasound.

Our experienced doctors guarantee the highest quality.

After week 30 we can see of the baby will be above average size at the time of birth. Babies with a large birth weight will also be large then.

We also examine the baby's development. We look at the organs to see if they function, as they should. It is however rather late in the pregnancy to look for malformations, as the baby is now so big that you simply cannot see all the details anymore. We recommend our malformation scan for this.

When is the best time to have a 3D/4D scan?

The best time is between weeks 26 and 34 and the optimal time is around week 28 to 32. This is when the amount of amnion fluid is at it's highest and therefore it's easier to see the baby. After week 34 the amount of amnion fluid gradually reduces and getting good recordings is harder. However the amount of fluid is different in all women, so with a some patience we usually get good pictures anyway.

If you choose to have a 3D/4D scan as early as weeks 13 to 17 you will be able to see the entire baby on the screen at once. It will be more active and jumps a bit around, if it's not napping. If the baby is situated very deep in the uterus we can usually scan vaginally to get better pictures. Foetuses don't start gaining much fat until the last trimester, so at this time in the pregnancy the baby will look a bit 'foetus' like.

After 17 weeks the baby has grown to a size where it will not fit on the screen and we see 'pieces' of the baby. The further along in the pregnancy the more new born the baby will look. After 17 weeks we only scan abdominally.

The best conditions to good recordings are that the doctor scanning is very experienced and that there is a reasonable amount of amnion fluid.

In women with little amnion fluid the images will unclear. If the placenta is situated on the front side of the uterus it may get in the way of the ultrasound. We will then scan from the side of the tummy and that usually works out fine.

If the mother is overweight it many also lead to less clear pictures as fatty tissue blocks some of the ultrasound signals.
