Assessment of intracranial translucency (IT) in the detection of spina bifida at the 11-13-week scan.
OBJECTIVE Prenatal diagnosis of open spina bifida is carried out by ultrasound examination in the second trimester of pregnancy. The diagnosis is suspected by the presence of a 'lemon-shaped' head and a 'banana-shaped' cerebellum, thought to be consequences of caudal displacement of the hindbrain. The aim of the study was to determine whether in fetuses with spina bifida this displacement of th...
متن کاملIncreased fetal nuchal translucency at 11-14 weeks.
Nuchal translucency (NT) is the sonographic appearance of a subcutaneous collection of fluid behind the fetal neck. The measurement of fetal NT thickness at the 11-14-week scan has been combined with maternal age to provide an effective method of screening for trisomy 21; for an invasive testing rate of 5%, about 75% of trisomic pregnancies can be identified. When maternal serum free-beta human...
متن کاملFrom nuchal translucency to intracranial translucency: towards the early detection of spina bifida.
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...
متن کاملIntracranial translucency as a sonographic marker of open spina bifida at first trimester
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 ...
متن کاملPreliminary normal reference values of nuchal translucency thickness in Taiwanese fetuses at 11-14 weeks of gestation.
BACKGROUND To investigate normal reference values of nuchal translucency (NT) thickness in normal Taiwanese fetuses between 11 and 14 weeks of gestation. METHODS A prospective study of ultrasound measurements of fetal NT and crown-rump length (CRL) at 11-14 weeks of gestation was conducted in 724 consecutive Taiwanese fetuses between 1998 and 2001. The relationship between NT and 5-mm interva...
