background: central nervous system malformations are the second most common congenital malformations after congenital heart diseases. these malformations are associated with many instances of morbidity and mortality which underline the importance of prevention and their early diagnosis. objective: the objective of this study is the diagnosis of neural tube defect (ntds) in the first trimester a...

OBJECTIVE Measurement of intracranial translucency (IT), which is a recent earlier recognizable sonographic marker, has been suggested for detection of spina bifida. In this prospective study we aimed to determine normative values of IT in the population of Turkish singleton pregnant women during the first trimester of pregnancy. MATERIAL AND METHODS Between January 2011 and July 2011, all co...

Abstract Joubert syndrome (JS) is a rare autosomal recessive neurodevelopmental disorder that usually diagnosed late in pregnancy or postnatally based on pathognomonic midbrain–hindbrain malformation seen magnetic resonance imaging brain, which consists of the hypoplasia cerebellar vermis, thickened superior peduncles, and deepened interpeduncular fossa described as molar tooth sign. The recurr...

Spina bifida is the one of the most common severe congenital abnormality of the central nervous system. Scalloping of the frontal bones called “the lemon sign” and caudal displacement of the cerebellum called “the banana sign” are known as cranial signs of open spina bifida on ultrasonography at the second trimester. Although these signs are useful methods in diagnosing of open spina bifida in ...

The intracranial translucency (IT) is a recently introduced marker of open spina bifida (OSB). In this study, we describe a case of a fetus affected by Blake's pouch cyst which showed alterations of BS/BSOB ratio at the first trimester screening.

A 33-year-old woman, gravida 2, para 1, presented at a gestational age of 13 weeks 2 days for a routine 11to 13-week examination for assessment of the risk of chromosomal abnormalities. Her obstetric and medical histories were unremarkable. Her fetal biometric measurement (crownrump length, 61 mm) and nuchal translucency (1.8 mm) were normal. In the midsagittal view of the posterior brain, the ...

Title: Normal intracranial translucency values during first trimester gestation in regional south Indian population: cross sectional study.Background: Pregnancy is associated with a plethora of changes, which has to be monitored regularly diagnostics like ultrasound, however the shortcomings US requires alternatives such as detect anatomic malformations fetus.Estimate normal reference screenin...

It is now clear that the vast majority of major fetal abnormalities can be diagnosed prenatally by ultrasound, that most of these abnormalities can be detected in the first trimester of pregnancy and that women want firsttrimester rather than later diagnosis. It is also clear that effective diagnosis of fetal abnormalities often necessitates the identification of easily recognizable markers whi...

Methods During a 3-year period from 2012 and 2015, consecutive women undergoing first-trimester screening for aneuploidy were routine examined for the presence of the IT in the sagittal plane of the fetal head by one FMF-accredited MFM specialist. The anterior-posterior diameter was measured and normative data were generated. Fetuses with increased IT were further studied with serial scans and ...

The purpose of this review was to suggest practical criteria for the clinical translucency evaluation of direct esthetic restorative materials, and to review the translucency with these criteria. For the evaluation of reported translucency values, measuring instrument and method, specimen thickness, background color, and illumination should be scrutinized. Translucency parameter (TP) of 15 to 1...
