What’s the difference between 2D ultrasound, 3D ultrasound, and 4D ultrasound?

Isn’t technology wonderful? Remember the days when the only peek at your little bundle was in 2D? With 3D and 4D imaging, our photos can show so much detail! As you know, a 2D image will show your baby in black and white, and usually in profile form. 3D imaging contains color images where you can see your baby’s every detail. As early as 16-21 weeks, you can see your baby’s tiny fingers, nostrils, and even catch them smiling at you! 4D imaging shows your baby’s movement in 3D, so the next time you feel your ribs being poked, 4D imaging will show you if it came from his/her foot, hands, or elbow!
