Prenatal ultrasounds are a part and parcel of obstetrical care. Earlier these tests were done with the help of 2D ultrasounds. They are helpful in confirming pregnancy; determine the age of gestation, the approximate fetal size and location of the placenta.
The much modern 3D and 4D ultrasounds help us to get a deeper picture of the pregnancy. The probe can now multiple images and arrange them in 3D format. These images then become dynamic in nature with the help of 4D ultrasounds The ultrasound images now reveal movements and even facial expressions in the images.
Many obstetricians do not believe in 3D or 4D ultrasounds and label them as mere ‘entertainment’ only. These doctors still use the 2D ultrasounds. But contrary to their views, 3D and 4D ultrasounds do have some real benefits. The 2D ultrasounds do have some limitations diagnostically. The 3D ultrasounds do give out better images and clearer picture of certain areas.
2D ultrasounds can detect some birth defects but the more complex ones can be diagnosed with the help of 3D only. 3D and 4D ultrasounds can easily detect birth defects like clubbed feet, facial abnormalities and polydactyl. Spina bifida can be easily detected through the 3D or 4D scans.
There is an emotional factor involved too when you are using 3D or 4D scans. The bonding starts earlier on. The sex of the baby can be determined at a very earlier stage through the 3D or 4D scans and the parents start bonding with the unborn baby. The parents start thinking names for the baby and the joy of seeing the tiny movements of the baby and the little facial expressions can not be put into words.
3D ultrasounds help a mother, both emotionally and mentally. The mothers feel comfortable to know that the pregnancy and the development of the baby are progressing on the normal lines. The 3D ultrasound can easily detect any minor problems and the parents can take corrective measures from early on. Not to mention the special bonding that is developed between the mother and the child with the help of these 3D images. Though certain doctors around the world are still skeptical about the usefulness of 3D and 4D ultrasounds, the fact remains that 2D ultrasounds are the future face of medicine.
