Correlation 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 کاملAutomatic Gestational Age Estimation Based on Crown Rump Length and Gestational Sac
The development of ultrasound technology allows us to see the structure and development of the fetus directly. Crown-Rump Length (CRL) and mean diameter of gestational sac (MSD) can be used to determine the age of the fetus. Both parameters are useful for measuring different aspects of the first trimester of pregnancy. This study proposes a method to obtain those parameter values automatically ...
متن کاملCrown-rump length discordance in twins in the first trimester and its correlation with perinatal complications*
BACKGROUND A difference more than 15-40% in birth weight of twins can predict perinatal complications. As significant difference in twins growth has a very important effect on pregnancy and perinatal complications, this study aimed to evaluate crown-rump length discordance (ΔCRL) in the first trimester of pregnancy and its correlation with perinatal complications. METHODS A total number of 11...
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...
