A 3D ultrasound can be obtained at
any time during pregnancy, however the optimal time to have a 3D
Ultrasound is between 27 and 32 weeks. Earlier ultrasounds allow
mothers to see more complete images of their baby. Later 3D
ultrasounds reveal improved facial features since the developing fat
layer enhances these images. It is important to remember that all
images are dependent on the baby's position, movement, size, and the
amount of surrounding amniotic fluid.
Ultrasound has been in use for over 35 years and no harmful effects
have ever been shown from responsible use. Reputable and responsible
3D/4D centers limit scanning time to those much less than a typical
2D diagnostic scan. A 3D/4D ultrasound uses the same exact power
levels as the traditional 2D ultrasound and the FDA sets the
standard level that is safe to be used. While it is sometimes argued
by healthcare providers that 3D/4D ultrasounds are not necessary,
studies have shown a profoundly positive impact on parents and the
benefits to the pregnancy are significant.
When mothers are allowed to see a realistic view into the womb, the
pregnancy becomes more real and often causes mothers to take better
care of themselves. Fathers, extended families and siblings
experience a bonding through viewing a 3D ultrasound session that’s
known to produce a closeness during this very important time in all
their lives.
2D, 3D, and 4D ultrasounds are produced by listening to sound waves.
A 2D visualization is a single plane interpretation of the reflected
sound waves. 3D ultrasound is the same but at multiple angles. These
still images are created through a sophisticated software and shows
detailed features of the baby. 4D ultrasound is referred to as the
“4th dimension in time.” Instead of looking at a 3D still image, you
can view a real-time video with motion of the baby while still in
the womb.
There are several important factors involved when producing a 3D/4D
ultrasound. One factor is the amount of space remaining in the womb.
2D ultrasound sees through everything but when scanning in 3D,
everything becomes solid. Therefore things like the umbilical cord
or placenta can act as a barrier if sitting in front of the baby.
The most optimal time to see the baby is between 26 – 28 weeks
because there is still room in the womb. The further into the
pregnancy you go, the more the remaining space decreases. Another
important factor is how much amniotic fluid is present. It is
important to stay hydrated throughout the pregnancy. Extra fluid
intake a few days prior to coming in for a 3D/4D scan is known to
help with the clarity of the pictures. The placenta position is
another element that effects a ultrasound. An anterior placenta is
on the front side of the womb and in front of the baby while a
posterior placenta is on the backside of the womb and in back of the
baby. With 3D/4D imaging, the posterior is ideal, however it is
possible to capture the baby regardless of which you have and
neither have any health implications.
