The 3D and 4D scans are the latest developments in ultrasound imaging. 3D Ultrasound allows you to see your baby’s face in one picture, like in a photograph. It has added volume to the traditional 2D ultrasound while the 4D imaging provides the fourth dimension of time, so instead of just a snapshot of your baby’s face, you can see the face moving in real-time (smiling, opening and closing the eyes, yawning), just like in a videotape.
With this technology, you can see the features of your babies and observe their movements before they are even born. You can follow the development of your baby inside the womb, and you can see how their movements get more sophisticated as your pregnancy progresses.
At week 14, you can see your baby’s skin covering its internal organs. You can even see your baby’s nose and mouth, or see her yawn or stick her tongue out.
It is best to have 3D or 4D scan when you are between the 26th and 30th week of pregnancy. Before 26 weeks, your baby still doesn’t have much fat under his/her skin, so more often than not, the bones will show through the skin. It is best to wait until 28 weeks to get the best image of your baby.
Advantages of 3D & 4D Ultrasound in Pregnancy
3D/4D scan lets you easily identify your baby’s gender. The gender of the baby gradually shows at around the 12th week of gestation, but is generally during the 16th week that it can be determined with greater certainty. At the 26th week and onwards, the baby’s genitals can be seen clearly in the 3D or 4D scan.
The 3D images allows for the early detection of fetal abnormality, especially in the face, extremities, chest, spine, and central nervous system. It can help doctors determine the extent of the abnormality, and help parents better understand it.
4D scanning helps in monitoring the development of the fetal movements. Any alteration can indicate the existence of pathologies of the neurological system. In addition, the 3D and 4D ultrasound in pregnancy is safe.
Advantages of 3D and 4D in OB-Gyne
3D imaging is significant in the diagnosis of gynecological problems. Using it in combination with Doppler ultrasound can improve the diagnosis of tumors in cases of ovarian or endometrial cancer.
It can also be used to detect and assess ovarian cysts, ectopic pregnancies, ovarian cysts, uterine myomas, and endometrial polyps.
The 3D ultrasound has revolutionized the diagnosis of uterine malformations. A 3D scan is now sufficient to detect these problems without the patient being subjected to invasive techniques such as hysteroscopies or laparoscopies.
