Estimation of gestational age by transvaginal sonographic measurement of greatest embryonic length in dated human embryos. Written informed consent was not required and therefore not obtained. Conclusion Accurate dating of pregnancy is important to improve outcomes and is a research and public health imperative.

Predicting delivery date by ultrasound and last menstrual period in early gestation. This Committee Opinion outlines a standardized approach to estimate gestational age and the anticipated due date. However, patients record and the data were anonymized before analysis.

Mean sac diameter measurements are not recommended for estimating the due date. Accurate determination of gestational age can positively affect pregnancy outcomes.

The information should not be construed as dictating an exclusive course of treatment or procedure to be followed. Conclusions Systematic discrepancies were identified when biometric formulas were used to determine duration of pregnancy. Fetal Imaging Workshop Invited Participants. Accordingly, in creating recommendations and the associated summary table, single-point cutoffs were chosen based on expert review. However, this change has not yet been properly evaluated.

The primary outcomes were post-term and pre-term birth rates defined by different dating methods. Standardization of sonar cephalometry and gestational age. In Denmark, an effort to standardise pregnancy dating has been made through the establishment of a national guideline.

Comparison of pregnancy dating by last menstrual period, ultrasound scanning, and their combination. Last menstrual period versus ultrasound for pregnancy dating. Ultrasound for fetal assessment in early pregnancy. Accurate dating of pregnancy is important to improve outcomes and is a research and public health imperative.

First- and second-trimester ultrasound assessment of gestational age. This document reflects emerging clinical and scientific advances as of the date issued and is subject to change. Computer assisted analysis of fetal age in the third trimester using multiple fetal growth parameters. For the purposes of research and surveillance, the best obstetric estimate, rather than estimates based on the last menstrual period alone, should be used as the measure for gestational age.
