Standardisation of crown-rump length measurement.
Correct estimation of gestational age is essential for any study of ultrasound biometry and for everyday clinical practice. However, inconsistency in pregnancy dating may occur through differences in measurement methods or errors during measurement. In the INTERGROWTH-21(st) Project, pregnancies are dated by the last menstrual period, provided that it is certain and associated with a regular me...
متن کاملThe chromosome analysis of the miscarriage tissue. Miscarried embryo/fetal crown rump length (CRL) measurement: A practical use
OBJECTIVE To investigate whether miscarried embryo/fetal crown rump length (CRL) measurement may yield a practical application for predicting a conclusive result at the cytogenetic analysis of miscarriage tissue. Our study might help in improving the cytogenetic method, the results of which may be affected by maternal cell contamination (MCC). In particular, we aimed at establishing whether the...
متن کاملCorrelation between the Fetal Liver Length and Crown- Rump Length During the First Trimester Screening
Objective: The aim of the present study was to determine the correlation between fetal liver length (FLL) at the 11+0–13+6 week of pregnancy and crown-rump length (CRL). Methods: Pregnant women (n=63) referring to the Başkent University Konya Hospital Obstetrics and Gynecology Clinic between January and March 2014 for first trimester screening were included in the study. Patients were excluded ...
متن کاملCrown-Rump Length Measured in the Early First Trimester as a Predictor of Low Birth Weight
The aim of this study is to assess the association between crown-rump length (CRL) measured before the 10th gestational week and birth weight. Results from 316 transvaginal ultrasonography scans at the 46th, 53rd, 60th, 67th, and 74th days of pregnancy were compared in low birth weight (LBW) versus normal birth weight groups. A positive correlation between CRL and birth weight was observed when...
متن کاملNew first-trimester crown-rump length equations from a French general population.
INTRODUCTION The purpose of this study was to obtain precise knowledge of fetal biometric measurements, in particular crown-rump length (CRL). Our results have been carefully compared to equations found in the literature. MATERIALS AND METHODS Single-operator measurements of 2,123 spontaneous pregnancies from a general French population provided new statistical relationships between fetal age...
