Biparietal diameter (BPD) is a crucial fetal measurement obtained during OBGYN ultrasound scans. It measures the widest transverse diameter of the fetal head, specifically between the two parietal bones. This measurement is a key indicator of fetal growth and gestational age, especially in the second trimester, aiding in accurate dating of pregnancy and monitoring development.
As a fundamental biometric parameter in obstetric ultrasound, BPD is integral for assessing fetal well-being. Regular assessment of BPD helps healthcare professionals track growth progression, identify potential growth restrictions or macrosomia, and ensures optimal prenatal care.
