Summary
Ultrasound biparietal diameter measurements accurately track fetal growth during pregnancy. A new percentile curve from 4,170 measurements aids comparison with normal fetal development weekly.
Area of Science:
- Obstetrics and Gynecology
- Fetal Medicine
- Medical Imaging
Background:
- Ultrasound measurement of the fetal biparietal diameter (BPD) is a standard method for assessing fetal growth.
- Accurate fetal growth assessment is crucial for monitoring pregnancy health and identifying potential developmental issues.
Purpose of the Study:
- To establish a normative reference range for fetal biparietal diameter (BPD) measurements.
- To provide a tool for clinicians to compare individual fetal BPD measurements against expected growth patterns.
- To aid in the early detection of intrauterine growth restriction or macrosomia.
Main Methods:
- A retrospective analysis of 4,170 fetal ultrasound measurements.
- Data collected from 1,394 pregnant individuals.
- Construction of percentile curves for BPD based on gestational age.
Main Results:
- A detailed percentile distribution curve for biparietal diameters was developed.
- The curve covers weekly intervals throughout gestation.
- This provides a week-by-week reference for normal fetal head growth.
Conclusions:
- The developed percentile curve serves as a reliable reference for assessing fetal growth via BPD measurements.
- This tool enhances the clinical evaluation of fetal well-being during pregnancy.
- Standardized BPD charting improves the accuracy of fetal growth assessment.
