Fetal Parameter Discrepancy

Fetal growth parameters are biparietal diameter (BPD), head circumference (HC), abdominal circumference (AC), humerus length (HL), and femur length (FL). They help to evaluate fetal weight and fetal growth. Abnormal fetal growth is seen when there is a discrepancy seen between actual and expected biometric measurements for the given gestational age.
