Nuchal translucency scan
There are a number of tests and scans available to you during your pregnancy. The nuchal translucency scan is an ultrasound that may detect the risk of a number of chromosomal abnormalities. A nuchal translucency scan is part of the ultrasound scan that most pregnant women have at around 12 weeks of pregnancy. The results of a nuchal translucency scan may tell you if your baby has a high or low risk of a chromosomal abnormality. Examples of chromosomal abnormalities include trisomy 21 Down syndrome , trisomy 18 Edwards syndrome or trisomy 13 Patau syndrome. The results will tell you if your baby is at high risk or low risk of chromosomal abnormality in comparison to the general population. The nuchal translucency scan is done between 11 and 14 weeks of pregnancy. Usually the scan is done through your abdomen but occasionally the nuchal translucency can only be seen by inserting a probe into the vagina.

The nuchal translucency (NT) scan, or “week scan,” is an ultrasound performed with the patient’s date of birth and the first trimester biochemistry blood test.
This page has information about ultrasounds and pregnant women in the Northern Territory NT. It is recommended that you have an ultrasound at 18 to 20 weeks. You can also have one early in your pregnancy if you are wanting to have genetic testing done or to confirm dates. Your doctor or midwife will tell you if you need another ultrasound later in your pregnancy.
Your doctor or midwife can organise and discuss all ultrasounds that are recommended in pregnancy. A nuchal translucency ultrasound between 11 and 13 weeks and up to six days can be used to check if your baby has abnormalities.
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.
A Nuchal Translucency (NT) scan is a screening test that is carried out to of their dates are recommended to have a dating scan before the screening test.
The test suggests which pregnancies are at a higher risk of abnormality and may need further investigation. Alongside the scan we require you to have a blood test at least three working days prior. The pathology results and the scan measurements are used together to provide your report. We require you to have a full bladder during this scan. Please drink ml of water one hour before your appointment and try your best not to empty your bladder.
If you think you will find this difficult, please talk to us at the time of booking. You are not permitted to take photos or video during the scan. This is a medical procedure, and whilst we appreciate you are excited, the health of your baby is our primary concern and we ask for your support and understanding during this clinical appointment.
Due to the medical nature of the appointment we ask that you are accompanied by one person. Your Ultrasound will be performed by a Sonographer.

Early pregnancy scan (booking or dating scan)
Back to Your pregnancy and baby guide. All pregnant women in England are offered an ultrasound scan at around 8 to 14 weeks of pregnancy. This is called the dating scan. It’s used to see how far along in your pregnancy you are and check your baby’s development.
A nuchal scan or nuchal translucency (NT) scan/procedure is a sonographic prenatal screening while fatality is 19% at this size. A nuchal scan may also help confirm both the accuracy of the pregnancy dates and the fetal viability.
A nuchal translucency screening, or NT screening, is a specialized routine ultrasound performed between week 11 and week 13 of pregnancy. Fetuses with increased fluid at the base of their necks — a spot known as the nuchal fold — may have a chromosomal problem such as Down syndrome. Nuchal translucency is a prenatal screening , which means the results can’t tell you for sure whether your child has a chromosomal disorder, only the statistical likelihood.
It’s often combined with a blood test to offer more insight into the relative odds of your baby being born with a genetic disorder. An NT screen is often part of routine prenatal testing during the first trimester and is recommended for all women. While it’s widely available, some areas especially rural ones may not have the machine and technicians with the experience to perform the procedure.

The week pregnancy ultrasound scan, or nuchal scan, is the first routine scan of pregnancy. You can have this pregnancy scan in London in our private clinic as a one-off or as the start of an ongoing relationship where we will offer diagnosis and support throughout your pregnancy. The first trimester screening scan allows a close assessment of a baby’s anatomy and organs and can detect abnormalities that may be linked with Down syndrome or other major types of birth defects.
In most cases it is a confirmation that things are progressing normally; infrequently, this scan highlights an issue that requires closer observation.
Like other screening tests, an NT scan will not give a diagnosis, but the scan can We introduce the name of the patient, date and time of examination into.

For the new mum to be, Ultrasound scans are the highlight of her pregnancy. Ultrasound scans use sound waves to build a picture of your baby in the womb. The scans are painless, have no known side effects on mum or babies, and can be carried out at any stage of pregnancy. Talk to your midwife, GP or obstetrician about any concerns you have.
Nuchal translucency (NT) measurements in the first trimester screening During the scan, more than one measurement must be taken and the.
The scan applies ultrasound technology so the procedure is also non-invasive and painless. You will be scheduled for an ultrasound between 11 and 14 weeks into pregnancy. This timing ensures that the baby is not too small for the test to be effective, and not too developed that any surplus fluid is naturally absorbed. A scan of the vagina may afford a more precise view of the baby, especially if the test is taken early, but most NT scans are taken through the abdomen.
They then calculate the size of nuchal translucency, which appears on the scan as black between white lines of skin. They enter these figures into a record containing the general risk for mothers of this age, and both the age and measurements are then mixed to calculate an individual risk factor. Depending on the NT measurement, your risk can be greater or less than the general risk for women your age.
There is usually no reason why you cannot bring your partner, a friend or family member with you for support and to share the moment of seeing your baby. Anxiety is natural when getting the result, so extra support is always welcome. A diagnostic test like amniocentesis or CVS is able to provide a solid diagnosis, but these carry their own pros and cons, including a minor risk of miscarriage, and an NT scan is a safe way to help decide if you require a diagnostic test or not.
This is far less likely when the scan is accompanied by a blood test.
