Abstract

OBJECTIVE
This study was done to formulate Korean fetal biometry charts of midtrimester presenting percentile values as a function of gestational age. METHODS: The relationships between the ultrasound measurement of 5 fetal parameters (biparietal diameter, head circumference, abdominal circumference, femur length, transverse cerebellar diameter) and nuchal skinfold thickness and menstrual age were determined by a cross-sectional study. The study group consisted of 215 normal healthy pregnant Korean women with known last menstrual period and regular menstrual period who had been performed genetic amniocentesis at our hospital and for whom complete pregnancy outcome information was available. All ultrasound examination was performed by one expert examiner. For each of the 5 parameters, the 5th, 10th, 25th, 50th, 75th, 90th, and 95th percentiles were determined. RESULTS: Ready-to-use fetal measurement charts in midtrimester are presented in a format giving the percentile values as a function of gestational age. CONCLUSION: These fetal biometry charts, obtained from midtrimester, Korean women can be used as a reference value.
