Nuchal 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...
متن کاملNuchal translucency and gestational age.
Professor Wald and his team (Wald et al., 2004) have remodelled the already modelled SURUSS data (Wald et al., 2003a) to claim, firstly, that their results are now similar to those of the multicentre study co-ordinated by the Fetal Medicine Foundation (Snijders et al., 1998), and, secondly, that the gestation of choice for nuchal translucency (NT) measurement is 10 weeks. The latest modelling e...
متن کاملNuchal translucency thickness and crown rump length discordance for the prediction of outcome in monochorionic diamniotic pregnancies.
BACKGROUND Ultrasonographic features of the underlying hemodynamic changes in twin-twin transfusion syndrome (TTTS) may be present at the first trimester scan. AIMS To investigate the value of intertwin discordance in nuchal translucency (NT) thickness and crown-rump length (CRL) to predict TTTS and other adverse outcomes. STUDY DESIGN Cohort study. SUBJECTS One hundred and thirty-five un...
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 کامل[Increased nuchal translucency with normal karyotype].
Nuchal translucency (NT) measurement in first trimester screening between 11 and 14 weeks' gestation has now been clearly identified as a marker for aneuploidies and in particular for trisomy 21. Even in the absence of aneuploidy increased fetal nuchal translucency has been shown to be a marker for fetal heart malformations and numerous other fetal defects and genetic syndromes when the measure...
