What’s the difference between 2D and 3D ultrasounds?

What is the purpose of 3D ultrasound for pregnancy?
The Purpose of a 3D Ultrasound A 3D (third dimensional) ultrasound scan can show detailed pictures of your baby. These pictures are visually recognized by the orange/golden color and details of the baby’s face, eyes, nose, mouth, etc. 3D scanning can also be useful to look at the heart and other internal organs.
