Effects of ultrasound on maternal-fetal bonding: 2D vs. 3D/4D
D.H. Pretorius, K.M. Uyan, R. Neton, A. Hull, G. James & T. Nelson. 11th World Congress on Ultrasound in
Obstetrics and Gynecology. 12-28 October 2001. Melbourne, Australia.
Objectives: To compare the effects of two-dimensional ultrasound (2DUS) vs. three-dimensional ultrasound
(3DUS) imaging on the maternal-fetal bonding process.
Results: A randomized sampling of data was preformed to equalize cells for some study questions. Mothers
who received 3DUS shared their ultrasound photographs with significantly more number of people (mean,
31.72) than did mother receiving 2DUS (mean, 16.02). Subjects screened with 3DUS had a greater
tendency to form a mental image of the baby post-screening (82%) than 2DUS subjects (39%). The 3DUS
parents were more likely to receive comments on similarities/differences with the actual baby than parents
having 2DUS studies. Further, 70% of the mothers receiving 3DUS felt they ‘knew’ the baby right after birth
because of the images they saw compared to only 56% of 2DUS moms.
Conclusion: The 3DUS images appears to have a more positive influence on the perception of mothers
compared to 2DUS images. Specifically, mother who had 3DUS showed their images to twice as many
people as those having 2DUS studies. 3DUS may have the potential benefit to strengthen the support
system for families expecting their newborns.
