2D ultrasounds are the traditional black & white ultrasounds that you have probably seen before. The pictures show the skeletal structure (outline) of the baby. You also get to see the baby moving in 2D! This is the type of ultrasound that was probably used for your diagnostic ultrasound. It is still the best technology for gathering measurements of the baby and ensuring that the baby is developing as expected.

3D shows the tissue of the baby, which is more like real pictures. We can see the roundness of the baby's face, the shape of the nose and the contours of the lips. The color is actually not the color of the baby, it is computer enhanced to make the pictures more appealing.

4D shows the tissue of the baby - as the baby is moving. This will provide moving clips of your baby in action! The 4D video clips of your baby are similar to the 3D pictures - but moving!
