A prospective study to assess the clinical impact of interobserver reliability of sonographic measurements of fetal nuchal translucency and crown-rump length on combined first-trimester screening
OBJECTIVE To examine the interobserver variability for fetal biometric parameters and to focus on how this variability affects the combined first-trimester screening test results. METHODS Sixty-four singleton pregnancies who were scheduled for combined first-trimester screening were investigated. Two experienced sonographers performed all examinations at the same visit.

متن کاملNuchal translucency in normal fetus and its variation with increasing crown rump length (CRL) and gestational age.
BACKGROUND Nuchal translucency (NT) is the fluid collection behind the fetal neck which can be measured by ultrasound at 11-14 weeks of gestation. Increase in the nuchal translucency thickness is associated with various congenital anomalies. OBJECTIVE To study the relationship between nuchal translucency thickness, crown rump length and gestational age in normal fetus. METHODS Prospective a...
