Nuchal translucency measurement in fetuses with spinal muscular atrophy.
OBJECTIVE Spinal muscular atrophy (SMA) is an autosomal recessive neurodegenerative disorder with a high carrier frequency in the general population. The severity of this disorder indicates the importance of early prenatal detection. In medical literature, there are a few published case reports of enlarged nuchal translucency (NT) measurement in association with a diagnosis of SMA in the fetus....
متن کاملScreening for trisomy 21 in monochorionic twins by measurement of fetal nuchal translucency thickness.
OBJECTIVE To determine whether in screening for trisomy 21 by measurement of fetal nuchal translucency (NT) thickness in monochorionic twin pregnancies it is preferable to use the higher, smaller or average NT. METHODS We retrospectively examined 769 monochorionic twin pregnancies that had undergone NT screening. The selection criteria were that first, in each pregnancy both fetuses were aliv...
متن کاملImage Settings Affecting Nuchal Translucency Measurement Using Volume NT™ Software
PURPOSE To evaluate the effects of the deviation from the mid-sagittal plane, fetal image size, tissue harmonic imaging (THI), and speckle reduction filter (SRF) on the measurement of the nuchal translucency (NT) thickness using Volume NT software. MATERIALS AND METHODS In 79 pregnant women, NT was measured using Volume NT. Firstly, the three-dimensional volumes were categorized based on the ...

INTRODUCTION To evaluate the performance of first trimester nuchal translucency scan screening among pregnant women in Nigeria. METHODS A prospective observational and questionnaire based study involving 510 pregnant women between 11(+0) and 13(+6) weeks. Routine counselling and nuchal translucency measurement was conducted using the FMF, London guidelines. Chorionic villous sampling was done...
متن کاملIncreased nuchal translucency in fetuses with a normal karyotype.
Sonographic assessment of nuchal translucency (NT) thickness has been recognized as an effective means of screening for trisomy 21 and other chromosomal abnormalities at 11–14 weeks of gestation. Up to 80% of aneuploid fetuses have increased NT, but this feature is also found in 5% of karyotypically normal fetuses at this stage of pregnancy (Snijders et al., 1998). As this screening test examin...
