The authors have compared the biometric measurement of the first trimester of gestation (CRL, gestation sac volume, GS vol./CRL ratio) with the respective weights at birth, in order to determine possible correlations. The result have showed no newborns SGA with biometric measurement greater than the 90 degrees percentile in the first trimester of pregnancy, and also no newborns LGA with biometric measurements smaller than the 10 degrees percentile. The authors nevertheless conclude for an insufficient prediction of the parameters considered, cause the high percentage of false positives and false negatives.
