Screening for fetal abnormalities with ultrasound

Area of Science:

• Perinatology
• Medical Imaging
• Genetics

Background:

• Fetal abnormality screening is crucial for prenatal care.
• Sonographic techniques are continuously evolving.

Purpose of the Study:

• To review recent literature on sonographic screening for fetal abnormalities.
• To identify novel techniques and refined screening tools.

Main Methods:

• Literature review of studies published in the past year.
• Analysis of advancements in first and second-trimester ultrasound screening.

Main Results:

• Growing interest in early fetal anatomy assessment alongside nuchal translucency.
• Tricuspid regurgitation and ductus venosus assessment as beneficial second-line aneuploidy screening tests.
• Exploration of frontomaxillary facial angle and refined nasal bone measurements for aneuploidy detection.
• Evaluation of second-trimester screening for congenital heart defects and trisomy 21.
• Readdressed role of nuchal translucency discordance in monochorionic twins.

Conclusions:

• Fetal abnormality screening is advancing with new techniques.
• Refinement of existing screening tools is ongoing.
• Clinical implementation of these evolving modalities requires further observation.
