Conclusion
In conclusion,
ultrasonographic detection of Down syndrome can be challenging.
To assess the fetal risk for Down syndrome,
maternal serum AFP levels and ultrasonographic parameters are used in combination.
NFT is generally accepted as the single best ultrasonographic parameter for detecting Down syndrome.
Moreover,
ultrasonographic detection of Down syndrome can be improved by using a combination of gender-specific biometric parameters.
In our opinion,
to reduce the false-positive risk assessment rate in male fetuses,
one should always keep the effect of gender on NFT measurements in mind,
especially in the population that has borderline NFT measurements (6 mm) and has no other anomalies.
