What makes 3D/4D ultrasounds different?

 

Like regular sonograms, these ultrasounds also use soundwaves to create an image of the embryo. A regular scan only creates a two dimensional picture which has a see-through quality to it (i.e you can see the organs through the skin of the baby in your womb). However, a 3D or 4D ultrasound uses these images to create a three dimensional life like image of the child. You can see the facial features clearly and you can see the baby move just like in a movie.

Who needs a 3D/4D ultrasound?

Parents are often very eager to have a 3d or a 4D scan. It is very exciting for the parent to see their child before the birth. Unlike regular two dimensional ultrasounds, 3D and 4D ultrasounds are optional. However in some cases, these scans do give out more information. In some rare cases, such as cleft palate or other birth defects, doctors also prescribe these scans.

 These days, the doctors do theses scans as a gesture of courtesy towards their patients.  Generally not all the doctors have the facility for 3D and 4D ultrasounds. You can check online to see if there is a facility nearby.

When Should I have my 3D/4D Ultrasound?

There are various opinions between doctors and medical practitioners as to when a 3D or a 4D scan should be done. Some say 27-32 weeks of gestation, others say the optimal time is 26-30 weeks. Basically any time after the second trimester and before the baby settles into position is a good time to get your 3D or 4D ultrasound done. The baby has still some space to move and there is enough fat to fill out her facial features.

From 19-24 weeks scans can be done for gender determination.

Some points to Remember:

●     All 3D and 4D ultrasounds are safe. But it is best to get it done from a professional and/or get a referral from your doctor.

●     Avoid places that only do these scans for showing you the baby’s face.

●     Too much of anything can be bad. Consult your doctor especially if you are going for a keepsake sonogram

●     These scans can be very expensive, so ask your insurance company if they cover the cost.
