BPD Calculator

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.
