Abstract

This study correlates crown-rump length (CRL) from the dating scan with placental thickness in the second and third trimesters to estimate gestational age. A prospective study of 200 pregnant women (7–36 weeks) compared CRL-derived gestational age with placental measurements. Significant correlations were found (r = 0.94 for second trimester; r = 0.38 for third trimester). Conclusion: For patients who missed the first-trimester dating scan, placental thickness in the second trimester can reliably estimate fetal age.
