Evolution of fetal ultrasonography

Area of Science:

• Obstetrics and Gynecology
• Medical Imaging
• Fetal Medicine

Background:

• Fetal ultrasound (US) has significantly evolved, enhancing diagnostic capabilities.
• Traditional 2D US is increasingly complemented by advanced imaging techniques.

Purpose of the Study:

• To highlight recent advancements in fetal ultrasound.
• To emphasize the impact of these technologies on fetal anomaly detection and disease management.

Main Methods:

• Review of evolving first-trimester ultrasound contributions.
• Integration of three-dimensional (3D) and 4D ultrasound for enhanced fetal morphology assessment.
• Analysis of data on fetal neck translucency measurements.

Main Results:

• Increased detection rates of fetal anomalies in the first trimester.
• Improved identification of aneuploidies and congenital heart defects via nuchal translucency.
• Enhanced fetal morphologic assessment using 3D/4D US, particularly for facial and cardiac structures.
• Better understanding of disease natural history, aiding postnatal care.

Conclusions:

• First-trimester ultrasound is crucial for early anomaly detection.
• 3D/4D US provides superior fetal morphological evaluation.
• Fetal US advancements significantly improve prenatal diagnosis and postnatal management of fetal conditions.
