Ultrasonographic measurement of fetal nasal bone length in the second trimester in Korean population.

Prenatal diagnosis - 1 Feb 2007

Jung Eui, Won Hye-Sung, Lee Pil Ryang, Kim Ahm

Abstract excerpt

OBJECTIVE: To establish the reference range of fetal nasal bone length (NBL) in the second trimester in the Korean population and to determine its clinical value in screening for trisomy 21. STUDY DESIGN: A total of 3019 consecutive fetuses at 16-28 weeks of gestation underwent ultrasonographic m...
