The Difference between 2D, 3D, and 4D Ultrasounds

Different Scan Types

The parents-to-be go through a joyful yet worrisome experience. From listing down the possible choices of names to choosing between which techniques of ultrasound to go for, new parents have a lot to decide upon. An ultrasound is crucial for providing the new parents-to-be with diagnostic information about the fetal growth, position and development. Ultrasound is an imaging technique which produces the images of a fetus using the sound waves. 

Where ultrasound provides with the image of the developing baby, it also helps in diagnosing the infections, swellings and causes of pains in the mother’s body. However, with the advancement in technology, the pregnancy clinics now provide you with a variety of ultrasound techniques. Where the traditional 2D ultrasound technique gives a grey and blurry image of the baby, the 3D and 4D ultrasound gives a more realistic picture of the infant. 

2D, 3D, 4D—which is better? 

Let’s start with identifying the basics of the three—2D ultrasound produces an image which only consists of the outlines of the body and a blurred image of the internal organs, for many parent sit doesn’t provide them with satisfactory results. 

As the name says it all, 3D ultrasounds give a picture in three dimensions. In three dimensions ultrasounds, you can see the face, skin, gender and shape of the facial features. The only difference between 3D and 4D ultrasound is that in 4D technique also tells you the expected time. The best and probably the most advanced part about 4D ultrasound is that it gives a moving picture of the baby. 

2D, 3D, 4D– safety level: 

The traditional 2D technique is considered to be highly secured as the exposure to waves is highly limited. 3D is as safe as 2D as it doesn’t involve employing additional medical equipment. The process of taking a 3D ultrasound is similar to the 2d technique; the only difference is between the image processing methods. In the 3D technique, a collection of various 2D images is taken and is converted into the 3D dimensional image through a computer software package. 

Since the frequency sound waves are quite high in both the 4D and 3D scans, most of the doctor’s advice against it as it can leave the baby more exposed to the waves. The only time a doctor would go for the 3D and 4D scan is when there’s a risk of any congenital disability or any health-related abnormality. Going for 4D and 3D scans for video souvenirs is not a medically safe option. Since both the 3D and 4D techniques use ultrasound energy and sound waves higher than the standardized levels, it could have potential impacts on the fetus.

Concluding thoughts: 

Addition of 3D and 4D ultrasound is one of the greatest innovations in reproductive technology. However, exposing the baby to diagnostic imaging is not what the doctors would suggest. If you are still indecisive about which technique to use, you can contact pregnancy professionals and specialist at Ultrasound Plus to book your next appointment and to acquire high-quality visuals and ultrasound results.
