  1. What is Biparietal Diameter (BPD)? Biparietal Diameter (BPD) measures the width of the fetal head, helping assess baby's development.
  2. Why is Abdominal Circumference (AC) important? Abdominal Circumference (AC) evaluates the size of the fetus's abdomen, critical for detecting growth patterns.
  3. How is Crown-Rump Length (CRL) measured? Crown-Rump Length (CRL) estimates fetal length from the head to torso, usually in early pregnancy evaluations.
