The 3D/4D Scan

Over the last few months, as I go for checkups, the doctor performs a 2D ultrasound scan of my growing uterus to monitor the baby's growth. This week, Elijah and I will go for a 3D/4D scan. A 3D scan is more than sending sound waves straight down and reflecting back. Instead the sound waves are sent at different angles which then returns echos that are fed into a sophisticated computer program which reconstructs a three dimensional image of the fetus. 3D scans allow us to see width, height, and depth of the image, but not movement.

This is where 4D plays a role. 4D is similar to 3D but adds the element of time. It brings still images to life and allows us to see movement as it is happening, rather than getting a delayed image.

There is some controversy surrounding this technology as it is fairly new (having been developed at Duke University in 1987). Some arguments claim it is harmful to the fetus because of the sound waves that intrude the uterus walls. However, there is no basis for this as neither the mother nor the fetus can hear or feel the ultrasounds produced. In addition, there has been no associated mental defects to the fetus or harm to the mother directly attributed to 2D or 3D ultrasounds. The intensity of the ultrasound waves is set into the machine so it does not exceed FDA standards. So contrary to common belief, 3D scans are not harmful in any way to the fetus or mother (unless thru excessive use, even then there is no conclusive evidence of harm).

To ensure we have the best doctor and equipment for 3D/4D scans, our obstetrician recommended Fetal Medicine & Gynaecology. This center specializes in fetal development and has the latest machines available for 3D/4D scans. They only entertain a client if they have been give a doctor's referral and will not accept walk-ins. Their office is in Jaya One and their website is www.fmgc.com.my.

The ideal time for a 3D scan is between 26 to 28 weeks, to get the best images. At this time the fetus is just the right size (without descending too far into the pelvis) and has the right amount of fluid surrounding it to provide the best image. Our appointment has been made for the end of week 26 (perfectly spaced between my regular doctor appointments).

As 'futuristic' parents, we believe it is important to use the latest technology that medical science has to offer. We believe this cutting edge technology will become common place in all pregnancies in the future and wanted to be one of the first to experience it. Stayed tuned for the update to follow the appointment!
