Ultrasound structural fetal anomaly screening: an update

Area of Science:

• Medical Imaging
• Prenatal Diagnosis
• Obstetrics

Background:

• Ultrasound screening for fetal anomalies became routine in UK maternity units by the late 1970s.
• Congenital abnormalities affect up to 5% of newborns.
• Current screening practices lack uniformity in timing and methodology.

Purpose of the Study:

• To review current knowledge on screening for common structural fetal anomalies.
• To discuss advancements in ultrasound techniques for improved screening accuracy.
• To focus on anomalies detected during the 11-14 and 18-23 week scans.

Main Methods:

• Literature review of existing studies on fetal anomaly screening.
• Analysis of established ultrasound protocols for specific gestational ages.
• Exploration of emerging technologies in prenatal imaging.

Main Results:

• Significant progress has been made in identifying structural fetal anomalies via ultrasound.
• New techniques show promise for enhancing screening accuracy and diagnostic capabilities.
• Variability in current screening practices necessitates standardization.

Conclusions:

• Ultrasound remains a cornerstone for detecting structural fetal anomalies.
• Continued research and technological innovation are crucial for optimizing prenatal screening.
• Standardized approaches to ultrasound screening can improve detection rates and patient outcomes.
