What is 3D/4D ultrasound test for pregnancy?

3D/4D ultrasound test for pregnancy is an ultrasound technique conducted during pregnancy to produce and identify life-like images and videos of the unborn fetus. This test shows the fetal movements of the unborn child. 3D/4D ultrasound scan is the latest ultrasound technology where an additional dimension is added to the normal 2D ultrasound image helping in visualizing the moving real-time image of your unborn child.

Parents go for this ultrasound scan to monitor the development of the fetus and also to identify certain birth defects like cleft palate or spina bifida that may be hard to identify in a 2D scan.

When is 3D/4D ultrasound for pregnancy done?

Ultrasound can be done multiple times during pregnancy to scan the different stages of pregnancy. A pregnant woman can undergo 3/4D ultrasound scan at any time during her pregnancy. However, she is recommended to undergo 3D/4D ultrasound sonography between 24 to 28 weeks after having a fetal anomaly scan at 18-22 weeks for best scan images, said an expert of a fertility clinic in Kolkata. During this time, it is possible to see a clear image of the fetus’s movements and whether the growth of the unborn is adequate or not.

If you are expecting twins, you are recommended to undergo a 3d/4D ultrasound at around 25 weeks.

Are 3D/4D ultrasound tests for pregnancy safe?

During 3D/4D scan, the fetus is exposed to the ultrasound beam only for a few minutes. Moreover, there is no radiation involved in this procedure. Hence, there are no concerns or risks involved in 3D/4D ultrasound tests if done for a limited period of time. The mother and the unborn child are both safe during this test, said experts of a top fertility clinic in Kolkata.

How is a 3D/4D ultrasound test for pregnancy done?

3D/4D ultrasound procedure is simple, as stated by an expert at the fertility clinic in Kolkata. A particular gel is applied to the pregnant woman’s tummy, while the patient is lying down. The gel helps to get images of the unborn baby by passing sound waves. Then the ultrasound transducer is moved around the tummy to get the images from different angles.


Before opting for 3D/4D ultrasonography,  it is always advisable to consult a doctor to know its implications, although no such harmful effects have been recorded in the past 20 years. Moreover, 3D/4D scan is a non-invasive procedure, and you don’t have to follow any post-test recovery procedures.
