“Where can I get my 4D scan done?” is a question many expectant Moms have. This website aims to bring together the growing number of facilities across South Africa who offer this special bonding experience. Click here for 4D service providers.

4D scans can enhance the parental bonding experience prior to the arrival of the new bundle of joy. Expecting parents and siblings can have a chance to see the baby and create this pre-birth bond which can be instrumental in drawing the whole family closer together.

 

What is the difference between a 2D, 3D and 4D scan?
A 2D scan displays 2 dimensions – height and width.
A 3D scan displays 3 dimensions – height, width and depth.
A 4D scan displays 4 dimensions – height, width, depth and movement.
A 4D scan is also referred to as “Live 3D” as the 4th dimension is time which is the actual movement of the baby.

What determines the quality of a 4D scan?
Timing – The best time to do a 4D scan is between 27 and 34 weeks.
Fetal position – The baby’s position can affect imaging. The baby can sometimes have its arms over its face or have its face against the placenta or uterine wall, making imaging of the face difficult.
Fluid – There must be fluid around the baby. The more fluid there is the clearer the images are.
Maternal tissue – An increased amount of maternal tissue can reduce the image quality.
Identifying the sex is usually easy but occasionally the baby may have its legs crossed or there may be umbilical cord lying in the area of interest. You can usually start identifying the sex during the second half of the second trimester.
Twins – The best time to do a 4D scan on twins is between 24 and 26 weeks.

From the moment you fall pregnant, you begin an incredible journey which changes your life in the most amazing, and sometimes challenging, ways. Imaging this new life to have a visual record from the first sighting to the very important diagnostic scans to the breathtaking 4D scan is something that this digital age has allowed us to do.

 

Here is a video showing some of these visual moments you may experience. This video is called “9 Months In The Womb” and was created by Ultrasound Dimensions (Medical and Maternity Ultrasound Centre – Dublin, Ireland)

 

 

There are 2 very important diagnostic scans that should be done during your pregnancy:

 

  1. Nuchal Translucency (NT) ultrasound scan
    The NT scan forms part of a screening programme for Down’s Syndrome. The thickness of the fluid behind the baby’s neck is measured. The measurment is taken between 11 and 14 weeks. Down’s babies usually have thicker nuchal translucencies. The NT measurement, combined with blood tests and the mom’s age, can calculate a risk for Down’s Syndrome.
  2. Fetal Anomaly ultrasound scan (Anatomy scan)
    The fetal anomaly scan is performed between 18 and 23 weeks. The main objective of this scan is to assess all the structural anatomy of the baby.

 

What is the gender of my baby? Is it a boy or is it a girl?
Determining the sex of your unborn child should be an easy enough task but it does tend to have some challenges. Various factors come into play. Increased maternal adipose can result in an image that is not too clear from resolution point of view. The umbilical cord sometimes lies in the region of interest hiding the gender. Sub-optimal ultrasound equipment can produce a poor quality image. An inexperienced person performing the scan can result in the incorrect gender being confirmed.

 

What does a baby boy look like on ultrasound?

When looking from the bottom up, it looks like a hotdog with the sausage hanging out the bun.

What does a baby girl look like on ultrasound?

Earlier in the pregnancy you see the 3 white lines. The middle line is usually longer than the outer 2 lines.

As the pregnancy progresses and the baby starts to develop fat the 3 white lines start looking more like a hamburger.
