Screening tests during pregnancy: 3D and 4D ultrasound scans

The standard common obstetric diagnostic scans are two dimensional (2D). However, with the latest 3D and 4D ultrasound technology, mothers are able to see their baby properly for the first time.

While 3D scans reveal still images of the baby in three dimensions, 4D scans (with time as the fourth element) gather 3D images of the baby continuously and transform it into a moving image – just like a movie. For these reasons, ultrasound scans has been shown to improve fetal-maternal bonding.

From a medical viewpoint, these 3D and 4D ultrasounds can be used to examine the baby’s heart and other internal organs. It can also give additional information about a known abnormality such as a cleft lip, which enables the doctor to prescribe a suitable treatment plan after birth.
