What’s the Difference between 3D and 4D Ultrasound Scanning?

Ultrasound, which uses high-frequency sound waves to create images of the inside of the body, has only been used more widely to view fetuses since the late 1970s. As this technology has improved, doctors have also introduced more advanced forms of ultrasound—especially 3D and 4D ultrasound scanning.

Difference Between 3D and 4D Ultrasound scanning

3D ultrasound scanning presents still images, and complex software is used to decipher the images, producing a three-dimensional image of the fetal surface. According to 3D ultrasound scanning, doctors can measure the height, width and depth of the fetus to diagnose problems such as cleft lip and spinal defects.

4D ultrasound scanning can provide moving images, generating a live video of the fetus to show its movement, whether it is thumb-sucking, eye-opening, or stretching. 4D ultrasound scanning provides more information about the developing fetus.

Importance of 3D and 4D Ultrasound Scanning

Physicians generally place greater emphasis on 3D and 4D ultrasound scanning because they reveal inherent detail, allowing them to diagnose observable external conditions that may not be present on 2D ultrasounds. Meanwhile, for the highest quality images of your baby, it's best to have a 3D or 4D ultrasound scanning between 27 and 32 weeks of pregnancy.
