Nuchal Translucency Thickness Measurement in Fetal Ultrasound Images to Analyze Down Syndrome. . The most salient pre-natal marker to identify DS during the early stages of gestation is the Nuchal translucency (NT) thickness. Accurate NT measurement from ultrasound (US) images becomes challenging due to the presence of speckle noise, weak . What is the nuchal translucency test? The nuchal translucency test (also called the NT scan) uses ultrasound to assess your developing baby's risk of having Down syndrome (DS) and some other chromosomal abnormalities, as well as major congenital heart problems. It's offered to all pregnant women, along with a blood test, in first-trimester . Nuchal Translucency Normal Range Chart. When the nuchal scan is done, the doctor will share the results with you. At that time, it is important to understand what a normal measurement is. For a baby that is between 45 mm and 84 mm in size, a normal measurement is anything less than 3.5 mm. The NT grows in proportion to the baby. Increased fetal NT thickness refers to the measurement of the vertical thickness in the midsagittal section of the fetus that is equal to or greater than a specific threshold. . the incidence of aneuploidy by nuchal thickness measurement was 7% with an NT between the 95th percentile for crown-rump length and 3.4 mm, 20% with NT between 3.5 mm .
The screening is a blood test that evaluates substances in the blood (analytes), and NT is a sonogram that looks at nuchal translucency in the back of the fetal neck. Noninvasive perinatal testing (NIPT) is a newer method that provides a result with a blood test only; a first trimester ultrasound is still recommended.DOI: 10.1080/03772063.2021.1972847 Corpus ID: 240520960; Nuchal Translucency Thickness Measurement in Fetal Ultrasound Images to Analyze Down Syndrome @article{Thomas2021NuchalTT, title={Nuchal Translucency Thickness Measurement in Fetal Ultrasound Images to Analyze Down Syndrome}, author={Mary Christeena Thomas and . While both measurements are at the level of the fetal head or neck, a nuchal fold thickness, which is only performed in the second trimester, should not be confused with a first trimester nuchal translucency (NT) measurement. If an enlarged second trimester nuchal fold measurement is obtained, next steps should include. Detailed anatomic study
The nuchal translucency (NT) is an ultrasound measurement defined as the collection of fluid under the skin behind the neck of the fetus obtained between 10 and 14 weeks’ gestation (crown–rump length between 38–45 and 84 mm) (Fig. 12.1).While some fluid is present in the nuchal space of all fetuses, regardless of chromosomal status, it tends to increase among .
An NT scan, or nuchal translucency scan, is a non-invasive ultrasound screening for Down syndrome and other genetic conditions during pregnancy. It’s usually done between weeks 11 and 14 of .

The measurement of nuchal translucency (NT) thickness in ultrasound images of the fetus at 11–14 weeks' gestation is used, in conjunction with maternal age, as an indicator of the risk of chromosomal defects 1, 2. Nuchal translucency thickness is measured manually by placing the ultrasound scanner cursors on the edges of the translucency .

Your nuchal translucency scan measurement is combined with a blood test to work out the ‘combined first-trimester screen’ result. The calculation also includes your age. The objective of the paper is to introduce a novel method for nuchal translucency (NT) boundary detection and thickness measurement, which is one of the most significant markers in the early screening of chromosomal defects, namely Down syndrome. To improve the reliability and reproducibility of NT measurements, several automated methods have been .
