If you are expecting, it can be hard to navigate the many different types of ultrasounds that can be done during pregnancy.  While all ultrasounds use soundwaves to ultimately create a picture of your developing baby, the finished product can range widely depending on the definition type that you choose. To help make the decision easier, we are here to explain the difference between 2D, 3D, 4D, HD, and 5D ultrasounds.

2D Ultrasounds

As the most common form of ultrasound, a 2D ultrasound creates a black and white image that shows the skeletal structure of the baby and makes the internal organs visible. The 2D ultrasound is most commonly used to diagnose the health of the baby. As the name implies, all 2D images are flat and have no depth to them.  It produces a two-dimensional image of the internal structures of the body, which can be used to diagnose conditions in various parts of the body such as the heart, liver, and reproductive system. 2D ultrasound is often used during pregnancy to monitor fetal development and diagnose any abnormalities.

3D Ultrasounds

Much like 2D ultrasounds, a 3D ultrasound uses soundwaves to develop an image of the baby inside of your womb. However, unlike the flat image given by a 2D ultrasound, a 3D ultrasound creates the appearance of a three-dimensional image of the baby. This allows the expecting parents to see their baby’s face, rather than just the outline of the face.  This type of ultrasound uses advanced technology to create a detailed, realistic image that can be used to identify structural abnormalities or to monitor the development of a fetus during pregnancy. 3D ultrasound is particularly useful in diagnosing conditions in the brain, joints, and blood vessels.

4D Ultrasounds

4D ultrasounds also create a three-dimensional image but provide the benefit of creating an effect like a live video. With this type of ultrasound, you could potentially see your baby smile or yawn in the womb because it compiles hundreds of images into a moving video.  4D ultrasound is a type of ultrasound that produces a three-dimensional image in real-time. This means that it shows the movement of the internal structures of the body, allowing medical professionals to observe the motion of the heart, blood vessels, and other organs. 4D ultrasound is often used to monitor fetal development and diagnose abnormalities in the fetal heart.

HD, HD Live, 5D Ultrasounds

As the most recent advancement in ultrasound technology, HD and HD Live (also called 5D ) ultrasounds allow us to capture even clearer, sharper images. These images are more defined and have better resolution.
