What do the abbreviations BPD, HC, and AC stand for in fetal biometry?

Explanation:
In fetal biometry, the measurements used to assess growth are specific dimensions of fetal structures. BPD refers to the biparietal diameter, the distance between the two parietal points of the skull measured across the head in an axial view. HC stands for head circumference, the measurement around the outer edge of the skull. AC is abdominal circumference, measured around the fetal abdomen at the appropriate cross-section level. These are the standard terms used in ultrasound to estimate gestational age and fetal growth. Other phrasings like brain parietal diameter or hemispheric circumference aren’t standard measurements in routine fetal biometry, and abdominal capacity or abdominal cavity describe spaces rather than a measured dimension.
