WebAug 5, 2024 · AC: Abdominal circumference; BPD: Biparietal diameter; EFW: Estimated fetal weight; FL: Femur length; HC: Head circumference; HL: Humerus length; SC-DCDA: Spontaneously conceived dichorionic diamniotic. Figure 4: Estimated percentiles for (A) EFW, (B) BPD, (C) HC, (D) AC, (E) FL, and (F) HL in ART-DCDA twins. WebHC/AC (Ratio of Head Circumference to Abdominal Circumference) Tables. Used between 15-42 weeks. Normal ratio: <36 weeks = 1:1 >36 weeks - ratio decreases as the AC increases. This ratio helps to differentiate between symmetric IUGR, asymmetric IUGR and a normally proportioned fetus. Symmetric IUGR - ratio is normal.
