Nuchal Translucency Screening

Nuchal translucency NT is the sonographic appearance of a collection of fluid under the skin behind the fetal neck in the first-trimester of pregnancy. The term translucency is used, irrespective of whether it is septated or not and whether it is confined to the neck or envelopes the whole fetus. In fetuses with chromosomal abnormalities, cardiac defects and many genetic syndromes the NT thickness is increased.

her routine dating scan, the scan should be performed for anatomy checks; the NT measurement and screening blood test are not required.

We will also look at the placenta, amniotic fluid and umbilical cord. Pregnant women are offered two routine ultrasound scans during pregnancy, this is called the Fetal Anomaly Screening Programme. The other routine pregnancy scan offered by the NHS is around 20 weeks of pregnancy called the Anomaly scan.

First trimester scans

The nuchal translucency NT refers to the pocket of fluid at the back of the fetal neck. The measurement of the nuchal translucency is part of the combined screening test for trisomy 21 and trisomy 18, called enhanced First Trimester Screen eFTS. An increased NT measurement increases the chance for other chromosome differences, additional genetic conditions, and can also be helpful to predict structural differences that might be more obvious later in pregnancy such as a heart defect.

At the time of the NT ultrasound, the sonographer or physician who does the scan can also accurately predict your due date, determine how many babies you are carrying and examine the early basic structural development of the fetus.

The Nuchal Translucency (NT) tends to be larger in a baby that might be affected by a The assessment of these elements (age, blood, scan) combined give us a Accurate dating of your pregnancy; Diagnosis of multiple pregnancy.

A nuchal translucency screening, or NT screening, is a specialized routine ultrasound performed between week 11 and week 13 of pregnancy.

This first routine scan is carried out for the following reasons:. It is not diagnostic. We also like to arrange this for around 12 weeks, but it can be performed between 10 and 14 weeks.

Since chromosomal abnormalities can result in impaired cardiovascular development, a nuchal translucency scan is used as a screening, rather than diagnostic, tool for conditions such as Down syndrome , Patau syndrome , Edwards Syndrome , and non-genetic body-stalk anomaly. There are two distinct measurements: the size of the nuchal translucency and the thickness of the nuchal fold.

Nuchal translucency size is typically assessed at the end of the first trimester, between 11 weeks 3 days and 13 weeks 6 days of pregnancy. All women, whatever their age, have a small risk of delivering a baby with a physical or cognitive disability. The nuchal scan helps physicians estimate the risk of the fetus having Down syndrome or other abnormalities more accurately than by maternal age alone.

Overall, the most common chromosomal disorder is Down syndrome trisomy The risk rises with maternal age from 1 in pregnancies below age 25, to 1 in at age 35, to 1 in at age In , Sequenom announced the launch of MaterniT21, a non-invasive blood test with a high level of accuracy in detecting Down syndrome and a handful of other chromosomal abnormalities. As of , there are five commercial versions of this screen called cell-free fetal DNA screening available in the United States.

Blood testing is also used to look for abnormal levels of alphafetoprotein or hormones. The results of all three factors may indicate a higher risk.

The chance of having a baby with the condition is one in 1, for women who are 20 years old, rising to one in for women who are 30 years old, and one in for women who are It doesn’t carry a risk of miscarriage as it’s non-invasive, but it doesn’t give a definitive answer.

The presence of a thickened NT, even if the karyotype is normal, can be associated with structural abnormalities.

This report may help increase the confidence of couples who are reluctant to terminate the pregnancy.

Normal babies accumulate fluid under the skin behind the head and neck between 9 and 14 weeks of pregnancy, however, excess fluid has been associated with chromosome abnormalities such as Down syndrome. The Nuchal Translucency NT tends to be larger in a baby that might be affected by a chromosome abnormality and it can be compared with what is expected for a baby of the same size NT Normal Range.

The levels can be assessed from a simple blood test taken from you either before or on the same day as the Nuchal Translucency ultrasound is performed.

We recommend having your 12 — 14 week scan at the same time, there are many benefits to this scan including:.
