The BPD (Biparietal Diameter) is a crucial measurement in prenatal ultrasound scans. It is used to assess fetal head growth and development, particularly in estimating gestational age and fetal weight.
Explanation of Key Terms
- Head Circumference (HC): The circumference of the fetus's head, usually measured in centimeters (cm).
- Abdominal Circumference (AC): The circumference of the fetus's abdomen, also measured in centimeters (cm).
- BPD (Biparietal Diameter): A measurement taken across the skull from one side to the other, used as a key parameter in fetal development assessments.
BPD Calculation Formula
The formula used in this calculator is:
\[ \text{BPD} = \frac{\text{Head Circumference} + \text{Abdominal Circumference}}{2} \]
Importance and Clinical Usage
BPD is an important biometric parameter for monitoring fetal health and predicting birth outcomes.
