To compare the size of error in the predicted date of delivery by biparietal diameter (BPD) and last menstrual period (LMP) in different clinical models.

To compare the dates of delivery predicted by last menstrual period (LMP), crown–rump length (CRL) and biparietal diameter (BPD) with the actual date of delivery in a population of pregnant womenExpand
Estimated date of delivery based on second trimester fetal head circumference: A population‐based validation of 21 451 deliveries
TLDR
Assessment of the actual pregnancy length and accuracy of EDD prediction based on fetal head circumference measured at the second trimester. Expand
A discrepancy between gestational age estimated by last menstrual period and biparietal diameter may indicate an increased risk of fetal death and adverse pregnancy outcome
Objective To determine if the discrepancy between gestational age estimated by last menstrual period and by biparietal diameter (GALMP− GABPD) is associated with adverse pregnancy outcome.

To introduce a direct population‐based method for prediction of term based on ultrasound measurements of the biparietal diameter and femur length in the second trimester of pregnancy.
Fetal age assessment based on ultrasound head biometry and the effect of maternal and fetal factors
TLDR
The aim of the present study was to establish new reference charts for gestational age assessment using fetal biparietal diameter (BPD) and head circumference (HC), and to determine the effect of maternal and fetal factors on age assessment. Expand

TLDR
The objective of this study was to determine how GA can best be estimated by fetal ultrasound for women who present for the first time late in pregnancy with uncertain or unknown menstrual dates. Expand
Biases in second-trimester ultrasound dating related to prediction models and fetal measurements
TLDR
Rutineundersokelsen med ultralyd rundt svangerskapsuke 17–19 har vaert en viktig del av €20,000 ved ULTRALYD-BASERT TERMINFASTSETTELSE. Expand
Accuracy of second trimester fetal head circumference and biparietal diameter for predicting the time of spontaneous birth
TLDR
Provided that the expected pregnancy duration was 282 days, both HC and BPD predicted spontaneous birth with a mean accuracy of one day, HC being significantly better than BPD. Expand
The use and accuracy of manual and electronic gestational age calculators
TLDR
A procedure for validating device accuracy is devised for gestational age (GA) wheels use and the inter‐observer and inter‐device variability of a range of devices is determined. Expand
Dating of Pregnancy in First versus Second Trimester in Relation to Post-Term Birth Rate: A Cohort Study
TLDR
Systematic discrepancies were identified when biometric formulas were used to determine duration of pregnancy and should be corrected in clinical practice to avoid an overestimation of post-term birth and unnecessary inductions when first trimester formulas are used. Expand
