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 کاملFetal heart assessment in the first trimester of pregnancy: influence of crown-rump length and maternal body mass index
OBJECTIVE To evaluate the influence of the crown-rump length and body mass index on sonographic evaluation of the fetal heart using abdominal and vaginal routes in the first trimester of pregnancy. METHODS We conducted a cross-sectional study with 57 pregnant women between 12-14 weeks (CRL< 84 mm). We evaluated the following fetal cardiac plans using the abdominal and vaginal routes: four-cha...
متن کاملStandardisation 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 کاملInternational standards for early fetal size and pregnancy dating based on ultrasound measurement of crown–rump length in the first trimester of pregnancy
OBJECTIVES There are no international standards for relating fetal crown-rump length (CRL) to gestational age (GA), and most existing charts have considerable methodological limitations. The INTERGROWTH-21(st) Project aimed to produce the first international standards for early fetal size and ultrasound dating of pregnancy based on CRL measurement. METHODS Urban areas in eight geographically ...
متن کاملThe Relationship Between Fetal Crown- Rump Length in the Early First Trimester and Growth Parameters at Birth
Materials and Methods: This was a prospective, cohort study in Hajar Hospital of Shahrekord, southwest Iran from March, 2013 to June, 2014 (within 15 months). Thirty women achieving pregnancy with intrauterine insemination and in vitro fertilization were compared with 60 women getting pregnant naturally.
