3D / 4D Ultrasound Imaging

Ultrasound is an imaging method that used sound waves to create images of a baby in a pregnant mom. It does not use ionizing radiation and has no harmful effects.

How does a 3D ultrasound work?

While Standard ultrasound (2D) uses sound waves to create of your baby in your womb, it sends and receives ultrasound waves in just one plane. The reflected waves provides a flat, black and white image of the fetus in that plane, the 3D ultrasound however, shows the images in three dimensions. 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. Like regular ultrasounds, 3D and 4D ultrasounds also uses sound waves to create an image of your baby in your womb.

What is the difference between 3D and 4D ultrasound?

3D ultrasound is a scanning method that creates a three-dimensional images of your baby which provides a clearer image compared to a regular or standard ultrasound (2D). It allows fetal structures and internal anatomy to be visualized as static 3D images while 4D ultrasounds create a live-video effect of the images. 4D scans allows you to see your baby’s movement while inside the uterus.  You can watch your baby smile, yawn, move their arms and legs. It is basically a 3D ultrasound in live motion.

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

3D / 4D scan can be done anytime during the entire pregnancy but it is recommended and best done at second trimester, around 24 – 28 weeks of pregnancy.
