-D, 3-D, and 4-D ultrasounds: What’s the difference?
All ultrasounds use sound waves to create an image of your baby in the womb:
A regular 2-D ultrasound creates a cross-sectional view of your baby.
In a 3-D ultrasound, many 2-D images are taken from various angles and pieced together to form a three-dimensional image. This looks more like what you’re used to seeing in a typical photograph.
4-D is similar to 3-D, but it shows movement, so you can see your baby kicking or opening and closing their eyes.
So why don’t we use 3-D all the time if we have the capability to do so? Simply, 2-D often is more efficient. We usually don’t need 3-D to assess how your baby is developing. While 3-D can give a nice picture of the outside of your baby, 2-D ultrasound is really the standard that has been developed by experts to look for abnormalities in development and growth of your baby.
However, 3-D and 4-D ultrasounds can be important tools to assess some abnormalities that are hard to look at in 2-D, such as cleft lip. They also are helpful when we need to explain an abnormality to parents. While doctors and sonographers may be able to easily recognize it in a 2-D image, parents are often able to better visualize the abnormality in a 3-D image.
Qualifications of the person performing the ultrasound
If you get a 3-D or 4-D keepsake ultrasound outside of a medical setting, the person performing the ultrasound is focused on getting a good photo and video for you, not assessing the health of your baby. They may not have the same rigorous training that a certified ultrasound facility requires of its sonographers.
If they see something they are uncomfortable with, they may not be prepared to provide you with information, support, or follow-up. In those cases, you may need to go to your doctor for another ultrasound. This can result in unnecessary anxiety and concern.
Commercial ultrasounds also may result in false reassurance. Some women interpret a pleasing photo as evidence of healthy development. If the person assessing the ultrasound isn’t a trained medical professional, they may not have the skills to notice that something isn’t right with the baby or other structures like placenta and umbilical cord.
Commercial 3-D and 4-D ultrasounds are not cheap! And having a baby is expensive these days. Don’t skip a recommended ultrasound or other testing at your doctor’s office just because you got a keepsake ultrasound and believe everything is fine with the pregnancy. Think about how you might otherwise use the money you would save from choosing not to have a keepsake ultrasound – like purchasing diapers or starting a college fund!
I already mentioned why there are concerns about the use of ultrasound with developing fetuses. I worry that the person performing a commercial ultrasound isn’t as careful about lowering the power settings on the ultrasound machine or keeping the time the baby is being exposed to a minimum.
Berikut ini adalah penjelasan tentang D-3 dalam Kamus Singkatan
Are ultrasounds safe for your baby?
The ultrasound waves used to image the baby expose the baby to energy in the form of heat. Under some circumstances, heat can lead to birth defects. That’s why we adhere to a principle while performing ultrasounds called ALARA: as low as reasonably achievable. That means we are careful with the settings on the ultrasound machine so we use as low amount of power as necessary and we limit the amount of time needed to obtain images, thereby exposing the developing baby to the least amount of energy possible.In its warning against commercial use of ultrasound, ACOG endorsed this statement from the American Institute of Ultrasound in Medicine: “Although there are no confirmed biological effects on patients caused by exposures from present diagnostic ultrasound instruments, the possibility exists that such biological effects may be identified in the future. Thus ultrasound should be used in a prudent manner to provide medical benefit to the patient.”Bottom line: When ultrasounds are performed to help manage the pregnancy and gather information about the developing fetus, I have no worries about its use.
Concerns about keepsake ultrasounds
Forty weeks can feel like a lifetime to wait to see your baby. 3-D and 4-D ultrasounds can seem like the perfect solution to get a sneak peek of your little one. Upon seeing one of these ultrasounds, I’ve heard parents say, “Oh, he’s got his grandfather’s nose,” or, “She looks just like her sister when she was born.”But when you go outside the medical setting to get a 3-D or 4-D ultrasound, we worry about a couple things.

Tuliskan komentar anda mengenai D-3 (diploma tiga)!
Dalam dunia pendidikan dikenal sebuah jenjang pendidikan diploma dua dan diploma tiga. Selama ini, pengguna bahasa tampak tidak seragam dalam menuliskan kata tersebut. Di satu pihak, ada yang menuliskannya dengan singkatan D2 dan D3 (tanpa tanda hubung), di lain pihak ada pula yang menuliskannya dengan D-2 dan D-3 (dengan tanda hubung). Dari kasus tersebut, manakah penulisan yang benar dengan atau tanpa tanda hubung?
Sebagai pengguna bahasa yang baik, untuk menjawab pertanyaan itu perlu dijelaskan bahwa sesuai dengan kaidah Ejaan Bahasa Indonesia yang Disempurnakan, tanda hubung mempunyai beragam fungsi. Salah satu fungsi tanda hubung itu adalah merangkaikan. Misalnya seperti pada contoh berikut, se-Jakarta, ke-2, 4000-an, dan hari-H.
Dalam contoh yang ke-2 dan 4000-an tersebut tampak bahwa perangkaian ke- dengan angka dan angka dengan –an, dilakukan dengan menggunakan tanda hubung. Hal itu menunjukkan bahwa perangkaian angka dengan unsur lain yang tidak sejenis (bukan jenis angka) dilakukan dengan membubuhkan tanda hubung. Selain itu, pada contoh yang hari-H tampak pula bahwa singkatan berhuruf kapital dengan imbuhan atau kata juga dirangkaikan dengan tanda hubung. Hal ini mengindikasikan bahwa singkatan berhuruf kapital jika dirangkaikan dengan unsure lain yang tidak sejenis juga ditulis dengan menggunakan tanda hubung.
Sesuai dengan penjelasan tersebut, jenjang akademik diploma tiga jika disingkat lebih tepat ditulis dengan menggunakan tanda hubung yaitu D-3, bukan D3. Huruf D pada singkatan itu merupakan singkatan berhuruf kapital yang dirangkaikan dengan unsur lain (angka 3) yang tidak sejenis. Angka 3 pada singkatan itu juga digabungkan dengan unsur lain yanmg tidak sejenis, yaitu D. Oleh karebna itu, perangkaian kedua unsur yang tidak sejenis itu lebih tepat menggunakan tanda hubung.
Hal yang sama juga berlaku bagi jenjang diploma dua dan diploma satu, yang disingkat menjadi D-2 dan D-1, bukan D2 dan D1. Angka di belakang singkatan D itu tidak menyatakan jumlah (seperti P3=3P). Dengan demikian, angka 1, 2, dan 3 pada D-1, D-2, dan D-3 bukan berarti 1D, 2D, atau 3D, melainkan menyatakan tingkat pertama, kedua, dan ketiga.

A quick Google search reveals that nearly a dozen businesses in the Dallas-Fort Worth area offer 3-D and 4-D keepsake ultrasound services.
More expecting parents than ever are paying to get photos and videos of their babies that are more lifelike than the 2-D ultrasounds from their doctor’s offices. This is despite the fact that the Food and Drug Administration (FDA) warns parents to avoid them. Medical groups such as the American Congress of Obstetricians and Gynecologists (ACOG) also discourage the use of commercial ultrasounds.
I know you’re excited to see your baby. Booking a photo op can be tempting. But it’s important to remember that an ultrasound is not just for entertainment. It’s an important medical test. Let’s talk about why and when doctors use them, and I’ll share my concerns about having a 3-D or 4-D ultrasound in a non-medical setting.
