Difference Between 3D and 4D

Research has shown that over 70% of pregnant women will have an ultrasound scan during their pregnancy. The old version of the ultrasound is 2D. However, with the advent of technological advances and production of modern equipment, the old version has been replaced with 3D and now 4D images. The 2D images are blurry, and it is often all gray. The photo shows the internal organs of the baby; however, the modern 3D and 4D images will show the actual image of the baby. With the new ultrasound system, you can see the shape of the baby’s nose and mouth. Then what are the differences between 3D and 4D ultrasound?

Difference Between 3D and 4D Ultrasound: Image

The three dimension image or 3D is a still image; on the other hand, 4D incorporates time dimension to it. Therefore, 4D is just like a video. A 3D scan will show the facial features such as the ears, nose, and mouth. The image is created by taking the scan results from different angles. This requires computer software because you have to put all the dimensions of the image into perspective. So a 3D image is more vivid and has depth. However, 4D image scan shows what the baby is doing in the womb. With this, you can see the baby yawn or change positions.

Medically speaking, the benefits of 3D and 4D scans over the original 2D images are limited, they are occasionally used in identifying if there is any abnormality. The scan can show different angles of the baby. Therefore, the doctor can identify any changes or deformity in the baby. Some of the conditions or deformities that can be seen with the 3D and 4D images include spina bifida, cleft lip, clubfoot, and deformities in the skull among others.

Whether you are utilizing 3D or 4D, the best time to take these scans is when you are 26-30 weeks pregnant. Before the 26th week of pregnancy, the baby’s face is not yet fully developed. After the 30th week, you may not see the baby’s head because it is often going towards the pelvis.

Difference Between 3D and 4D Ultrasound: Safety

Recent research studies indicate that 3D and 4D ultrasounds do not cause any harm to the pregnant mother and the baby. The ultrasound scan is usually important for the bonding between the mother and the baby. The doctor can also use the information to identify any deformities or problems with the baby.

Nowadays various companies have come up with modern devices to give 3D and 4D scan. However, many of them don't have qualified technicians. American Congress of Obstetricians and Gynecologists and American Institute of Ultrasound in Medicine say that you should not over expose yourself to the rays too much. So try to keep the ultrasound in a minimum and always choose a professional hospital.

There are some concerns that the 4D ultrasound scan may be more harmful than the 3D one. Studies have shown that the risk is not because of the ultrasound itself because there is no significant difference between 4D and 3D ultrasounds. The risk is often associated with prolonged exposure to the rays in the 4D ultrasound scan. It is recommended that you seek the services of a professional in the field because he or she will know how to operate the machine and the level of exposure that you can be allowed to experience. Do not conduct or carry out ultrasound for a longer period than it is necessary.

Final Verdict

Ultrasound can give the parents a glimpse of the baby. With the ultrasound, the doctor can check all the deformities and any changes that occur to the baby. Whether you want a 2D, 3D or 4D, you should weigh the merits and demerits before taking one.

Here is a video to show the 3D and 4D ultrasound of a baby girl.

Difference Between 3D and 4D Ultrasound: Cost

Both 3D and 4D ultrasounds are commonly not covered by the healthcare insurance. It is essential to understand that 4D ultrasound is more expensive than the 3D ultrasound. The price increases because of not only the high cost of equipment, but also the high power processing speed. 4D ultrasound can bring the images out quickly and create a real-time video. In most cases, a 3D scan costs between $125-$150 per session depending on location, while 4D image will cost $165- $225 per session.
