12 Week Scan

Book now. Every woman who is pregnant will be told about the nuchal scan as a way of detecting downs syndrome. In expert hands this nuchal screen alone can be very effective. With greater expertise, more anatomical checks can be made to give greater accuracy and rule out other anatomical conditions that may affect the pregnancy. The risk result will be individually calculated, based on maternal age, how pregnant you are, the nuchal translucency measurement and up to 4 additional ultrasound chromosomal markers. If your NHS scan fails to obtain the Nuchal measurement, then we advise you to call us immediately for an instant appointment. It is important to be seen, where possible before 14 weeks pregnant. We ask that you drink a pint of water one hour before the scan so that your bladder is full. This helps us to see the baby more clearly. We will show you everything we see as we go along, nothing is kept hidden from you and we will give you a picture for you to share with loved ones.

Fetal nasal bone length in the second trimester: comparison between population groups from different ethnic origins. To compare normal ranges of ultrasonographically measured fetal nasal bone length in the second trimester between different ethnic groups. A prospective, non-interventional study in order to establish normal ranges of fetal nasal bone length in the second trimester in a Greek population was conducted in singleton fetuses between 18 completed weeks and 23 weeks and 6 days of gestation.

The relationship between hypoplastic nasal bone with abnormal karyotype Second trimester ultrasound scan was performed at + six.

The starting point for the calculation of risk is your age at the time your baby is due. Thus the older you are then the higher the starting risk of your baby having Down’s syndrome will be. It is also important to note that a high risk screening result does not indicate with certainty that there is an abnormality and that most women with these results will still have normal healthy babies.

This examination has become extremely important in the early diagnosis of congenital anomalies and chromosomal disorders. Combined with 1st trimester biochemistry, it is the most sensitive, non-invasive risk assessment for aneuploidy currently available in Australia. The test should be preceded by appropriate counselling in all cases. All women are at risk of having an aneuploid fetus.

Many international professional organisations suggest the 12 Week NT Assessment be offered to all pregnant women regardless of age due to the benefits of early aneuploid detection and reduction in unnecessary prenatal invasive testing.

This combined test is an extremely accurate non-invasive screening test available to help identify a fetus at risk for Down syndrome as well as other chromosomal abnormalities and some major structural abnormalities. The sensitivity of this only recently eclipsed by NIPT. An ultrasound screening test is non-invasive and does not have any side effects or complications.

To be certain your NT scan is performed correctly, it is important that you have your scan performed at an accredited practice. A NT computer package was developed by the London Fetal Medicine Foundation in the s and was based on more than There is strict auditing of the NT ultrasound work performed by every accredited practice in the world. This ensures that the NT scan test is being performed correctly.

Recently, the Royal Australian College of Obstetricians and Gynaecologists has taken over regular auditing of Australian practices. Paradise Ultrasound has passed its audit since opening. However is best performed at 12 weeks.

The aim of this study was to evaluate the value of absent fetal nasal bone in the prediction of fetal chromosomal abnormalities, according to whether it was associated with other soft markers or structural abnormalities in a prescreened population of Chinese pregnant women. In this retrospective cohort study, women whose fetuses had absent nasal bone detected during the second trimester ultrasound scan were followed. Fetal karyotyping was performed and pregnancy outcomes were recorded.

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.

The laboratory services will provide the referrer with the combined screening risk after combination with first-trimester maternal blood results PAPP-A and hCG. If NT is required and cannot be obtained on the first attempt, consider a TV scan. A further separate attempt at NT may be made using section 88 code NF. More than two attempts on separate occasions is not recommended.

An ultrasound scan could save many mothers the decision over whether to have an amniocentesis and risk losing a baby.

Nearly two-thirds of week-old fetuses with Down’s syndrome lack a nasal bone, fetal-medicine specialist Kypros Nicolaides, of King’s College, London, and his colleagues found 1. This makes it unlikely that the test would wrongly diagnose Down’s syndrome. The nasal scan is more accurate than previous ultrasound markers, such as the length of leg bones. Some UK and US doctors are already using the nose-bone scan in combination with other tests.

The detection of Down’s syndrome requires a sample of fetal cells from the fluid surrounding the fetus. The nose-bone scan will reduce these tests, says Nicolaides. Women over 35 have a 1-in chance of having a Down’s syndrome baby.

To compare normal ranges of ultrasonographically measured fetal nasal bone length in the second trimester between different ethnic groups. A prospective, non-interventional study in order to establish normal ranges of fetal nasal bone length in the second trimester in a Greek population was conducted in singleton fetuses between 18 completed weeks and 23 weeks and 6 days of gestation.

Objective: To compare normal ranges of ultrasonographically measured fetal nasal bone length in the second trimester between different ethnic groups. Method: A prospective, non-interventional study in order to establish normal ranges of fetal nasal bone length in the second trimester in a Greek population was conducted in singleton fetuses between 18 completed weeks and 23 weeks and 6 days of gestation.

A literature search followed in order to identify similar studies in different population groups. Fetal nasal bone length mean values and percentiles from different population groups were compared. Results: Analysis of measurements in the Greek population showed a linear association, i. Eleven studies establishing normal ranges of fetal nasal bone length in the second trimester were identified.

Conclusion: Normal ranges of fetal nasal bone length in the second trimester vary significantly between different ethnic groups. Hence, distinct ethnic nomograms of fetal nasal bone length in the second trimester should be used in a given population rather than an international model.

Objectives: To assess the feasibility of measuring nasal bone length in first-trimester pregnancy and to confirm if the absence of a fetal nasal bone is a marker for Down syndrome. Methods: Fetal nasal bone assessment was attempted in consecutive singleton pregnancies between 11 and 14 weeks’ gestation.

All ultrasound examinations were performed transabdominally in three separate centers. If the nasal bone was present, nasal bone length was measured. Results: Nasal bone assessment was successfully achieved in of Within this group nasal bone was absent in 10 of 1. The nasal bone length in the five cases of Down syndrome in which the nasal bone was present was less than the median measurement of unaffected cases.

Conclusions: Absence of the nasal bone can be used as a marker for Down syndrome in the first trimester of pregnancy. Inclusion of the nasal bone in the current first-trimester screening protocol along with nuchal translucency, free beta-hCG and PAPP-A can achieve high detection at a very low false-positive rate. Large datasets are needed to confirm whether the measurement of nasal bone length provides additional benefits beyond the assessment of the presence or absence of the nasal bone.
