What’s the Difference Between 2D, 3D, and 4D Scans?
While a 2D ultrasound provides a grainy, flat image of your little one, 3D ultrasounds will show more detail. During the 3D ultrasound, multiple 2D images are taken from different angles, and these are rendered together to create a three-dimensional image of your baby. This scan can provide a clear image of the fetus, including the exact shape of the mouth, nose, cheeks, and eyes. The 4D images are similar, but they also show movement in the form of a short video. So, you might see your little one yawning, sucking a thumb, making cute faces, or opening and closing of the eyes.
