AI Article Synopsis
- Ultrasonographic volumetry can now measure fetal volume in the first trimester using 3D ultrasound systems, allowing for better monitoring.
- The study evaluated fetal volume growth over weeks, finding a strong correlation (r = 0.939) between fetal volumes and crown rump lengths across 72 first trimester pregnancies.
- A nomogram was created for fetal volume from 6-12 weeks gestation, which could be useful as a reference for diagnosing early pregnancy complications.
Article Abstract
Background: Ultrasonographic volumetry measurements of human fetus have become possible using three-dimensional ultrasound systems.
Objective: To evaluate the weekly increase of fetal volume during the first trimester of normal pregnancies compared to the crown rump length and creating a first trimester fetal volume nomogram.
Methods: Crown rump length and three-dimensional ultrasonographic volumetry measurements performed on 72 first trimester fetuses using virtual organ computer aided analysis (VOCAL).
Results: A significant direct correlation (r = 0.939) was found between the calculated fetal volumes and crown rump lengths. A 6-12 weeks gestation fetal volume nomogram was proposed.
Conclusion: Fetal volume database in the first trimester may serve as a reference table for diagnosis of early pregnancy failure.
