Ultrasounds are sound waves that, when they hit an object, bounce off and form a picture of that object. Ultrasound was first used in 1956 for medical purposes. However, an Italian biologist is most often credited with its invention in the late 1800s.

A two-dimension ultrasound, or 2D, is known as traditional ultrasounds as these are what was used in prenatal diagnoses before the recent invention of 3D and 4D ultrasounds. 2D ultrasounds will give you the outline of your baby and will look very flat. However, your doctor will be able to see the internal organs of the baby, which can help in diagnosing heart defects, kidney problems, and other prenatal conditions.

A three-dimensional ultrasound, or 3D, will allow you to see features of your baby, including facial features. These images are clearer, which allows doctors the ability to look for more conditions the baby may have, such as a cleft lip.

A four-dimensional ultrasound, or 4D, is comparable to a movie. You will have the clarity of a 3D ultrasound, but you can also see the baby move as well. These baby ultrasounds produce moving images of your baby, which we have to say, is pretty neat.

Why Get a Baby Ultrasound?
