3D/4D Ultrasound
A First Look!
Imagine seeing your baby yawn, stretch, or even smile at you—all while still in the womb. Advances in ultrasound imaging have led to the world of 3D/4D ultrasound technology. Used in conjunction with conventional 2D scanning, a 3D/4D ultrasound provides expectant parents with an extraordinary first look at their baby’s first movements in the womb. The experience has been described by many as “the most incredible thing we have ever done”. And while this technology generates a whole new level of excitement, it also generates some questions. What is it exactly? Is it safe for me and my baby? What can I expect? At what stage are the best images obtained?
What is 3D/4D ultrasound?
A 3D/4D ultrasound is similar to a traditional 2D ultrasound scan in that it uses the same ultrasonic sound waves to produce an image of your baby. With 2D ultrasound, the sound waves are rendered to produce a cross-section view, which most people are familiar with. You can generally see the outline of the baby’s head and hands, which is a miracle in itself, but you still can’t see your baby with any great detail.
With 3D/4D technology, however, the sound waves are rendered by the software in such a way that you can see your unborn baby with remarkable clarity. The fourth dimension is simply movement; three dimensional still images in rapid succession that create real time movement. The result is parents seeing breath-taking live action images of their children in mom’s belly. Parents have been able to see their child’s chubby cheeks, lips, arms, cute little fingers and adorable toes.
Is it safe for me and my baby?
3D/4D ultrasound uses the same safe ultrasonic waves as a 2D scan performed in the doctor’s office. Multiple studies have shown that when used properly, there is absolutely no reason to infer that 3D/4D ultrasound is any more or less intrusive to a fetus than 2D imaging. It simply processes the sound waves differently so that you can see your baby in an entirely new way.
That said, it is very important that you use an experienced, reputable 3D/4D ultrasound imaging center when seeking this technology. Not all facilities are created equal.
What can I expect?
When you compare the typical 2D imagery with the full movement provided by 3D/4D imaging, you will likely find that there are far more “oohs” and “aahs” with the latter. 3D/4D ultrasound can certainly provide you with an amazing look at your unborn baby as he or she lives and breathes in the comfort of your womb. Many factors can contribute to how well you see your baby. Your view will often be determined by your baby’s position, the location of the placenta, the amount of amniotic fluid, the type of equipment used and the skill of the ultrasound technician. If you intend to have a 3D/4D ultrasound performed, you should be well hydrated for your visit.
Many 3D/4D ultrasound facilities offer a welcoming atmosphere that encourages family and friends to attend. Some more advanced facilities are even offering you the option to share your experience with anyone in the world by streaming your session over the internet. This can eliminate the distance for families that may have a loved one serving in the military or living on the other side of the globe.
Although most reputable facilities will have highly-trained technicians, 3D/4D ultrasounds are not a replacement for your diagnostic ultrasound ordered by your healthcare provider. Most, if not all, facilities providing this type of ultrasound will require that mom is receiving prenatal care.
At what stage are the best images obtained?
This depends on what you are looking to see. If you are hoping to see full-body images, then it would be best to schedule your ultrasound between weeks 20-25. If you prefer to see more detail in your baby’s facial features, weeks 26-32 tend to be ideal. Outstanding images are possible beyond 32 weeks; however, the scan could be more difficult and views of the baby could be limited depending on conditions in the womb.
Friends and family members can often be a valuable resource in locating a reputable 3D/4D imaging center. Likewise, your Ob-Gyn or Midwife may be able to provide you with information on a highly regarded facility. Do your research. Many facilities have image galleries on their websites to give you an idea of the clarity of the images they produce. You can also search online referral sites for a facility near you. Ultimately your 3D/4D ultrasound experience should be one that you and your family will cherish for a lifetime.
