OBJECTIVE This study aimed to survey the current clinical practice of first-trimester ultrasonography among members of the Korean Society of Ultrasound in Obstetrics and Gynecology (KSUOG) and to provide basic data for making practical recommendations about first-trimester ultrasonography scan in Korea. METHODS This survey was conducted using a self-administered anonymous questionnaire. The f...

(1) Approximately three in every four fetuses with Down syndrome have increased nuchal translucency (NT), which is a larger than normal build-up of fluid at the back of the neck. (2) The ultrasound measurement of NT between 11 and 14 weeks' gestation, in combination with the mother's age and the levels of placental biochemical markers in her blood, can be used to detect approximately 84% of fet...

Objective To examine the association between increased nuchal translucency thickness and major cardiac defects in chromosomally normal fetuses. Setting Tertiary referral unit for fetal medicine and fetal

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...

background: to study the outcome of cases with nuchal translucency (nt) ≥ 95th centile in the first trimester of pregnancy. methods: this cross sectional study was performed at iranian fetal medicine foundation (fmf) between january 2009 and december 2011. totally, 186 cases with nt≥ 95th centile who attended for the first trimester screening were studied. all cases with increased nt including ...

OBJECTIVE First-trimester aneuploidy screening is in transition from the phase of 'development' to that of 'diffusion.' As with all other technologies, there is risk of diminished performance until newer centers are well experienced. Typically, inexperienced sonographers under-measure nuchal translucency (NT), and experience, training and continual monitoring of data are needed to ensure that m...

OBJECTIVE To examine the distribution of fetal nuchal translucency (NT) thickness in dichorionic twins and investigate the effect of the correlation between NT measurements in each twin pair on the performance of screening for trisomies. METHODS The distribution of fetal NT for crown-rump length (CRL) was examined in 5646 dichorionic twin pregnancies, including 103 with fetal trisomies 21, 18...

OBJECTIVE Many studies have shown that an increased nuchal translucency (NT) may be a good marker of fetal heart malformation, but the extent to which NT is suitable for identifying the population at risk remains unclear. We aimed to determine the value of NT measurement and of the presence of cystic hygroma colli in the screening of euploid fetuses for congenital heart defects (CHD). METHODS...

INTRODUCTION Numerous papers have proven that an increased nuchal translucency is connected with a raised risk of chromosomal aberrations, but few analyses are related to the further state of fetuses with a normal karyotype. THE AIM OF THE STUDY The aim of the study was to estimate the risk of cardiac defects and other developmental disorders in fetuses with increased nuchal translucency and ...
