Women also have routine blood tests or ‘blood screening’ to find out the mother’s blood group and several other things. For more information on screening tests please see ‘Resources ‘. Though all the pregnancies considered here began in the usual way with early scans and blood test screening, they all differed subsequently because the baby was found to have problems. See also ‘Having the week scan and further tests’. The first scan was to check the make-up of the baby – check that there was a heartbeat, check that their arms, legs, head and measure the length of the baby from crown to rump really. So that was what the first scan was for – a basic sort of check really – and I was told that they’re limited in what actually, if there is any abnormalities with the baby at that stage, they’re very limited about what they can actually find, it’s not really till the week scan where they’ll pick up most things, especially congenital deficiencies. The nuchal scan, we were given a leaflet, sent a leaflet by the hospital before we attended. My husband and I both attended the scan.
Nuchal Translucency Ultrasound
For all Obstetrics scans, no special preparation is needed, although it is best to wear loose clothing that can easily be lifted or removed in order to expose your abdomen. You will lie on your back on an examination couch and the transducer moved back and forth across your stomach in order to gain the best possible image of the fetus.
Ultrasound imaging in pregnancy is widely used to evaluate the baby. It can determine if a baby is present, the position of the fetus and if there is a multiple pregnancy. It can also help to diagnose abnormalities or problems, help determine the age of the pregnancy and subsequent due date as well as showing the position of the placenta in relation to the birth canal.
A nuchal translucency scan (NT scan) is an ultrasound screening test for assessing So the NT scan will usually happen alongside your routine dating scan.
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 assessment of these elements age, blood, scan combined give us a comprehensive understanding of the likelihood of your baby being affected by a chromosome abnormality.
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. The results can be compared to the expected results in a pregnancy at the same gestational age. We recommend having your 12 — 14 week scan at the same time, there are many benefits to this scan including:.
NHS and private ultrasound scans during pregnancy
This scan will also show if you are expecting a multiple pregnancy. Please drink 1 litre of water and hold for one hour prior to your appointment. Do not empty your bladder until after the examination.
Learn about anatomy, dating, biophysical profile, nuchal translucency scans, what Obstetric ultrasound, also known as prenatal or pregnancy ultrasound, uses.
This scan is carried out from 11 weeks to 13 weeks and six days. The scan is usually performed transabdominally but in a few cases it may be necessary to do the examination transvaginally.

This is particularly relevant for women who cannot recall the date of their last period, have an irregular menstrual cycle, or who have conceived whilst breastfeeding or soon after stopping the pill.
We measure the size of the fetus and from this we calculate the expected date of delivery. To diagnose multiple pregnancy. Ultrasound scanning can determine if both babies are developing normally and if the babies share the same placenta which can lead to problems in the pregnancy. In such cases it would be advisable to monitor the pregnancy more closely. To diagnose major fetal abnormalities.

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. Your doctor will supply a referral to one of the pathology clinics for this. It should be done atleast working day prior to the NT appointment. This combined test is a very 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.
An ultrasound screening test is non-invasive and does not have any side effects or complications. The only way to diagnose Down syndrome or other chromosomal abnormalities is by having a invasive diagnostic test — either a CVS or an Amniocentesis — and testing the fetal cells.

Pregnancy / Obstetric Ultrasound 3D & 4D Scans
An ultrasound scan sonogram uses sound waves that bounce off solid objects to create two-dimensional black and white images on a screen. It’s completely safe for you and your baby. It also isn’t completely reliable. When your bladder’s full, it pushes your womb up so the sonographer can see better. Most scans are normal.

A dating scan is performed around week 8 of pregnancy but can be done as early as 5 weeks. It is used to confirm due dates, assess the viability of the pregnancy, check the number of embryos, provide maternal reassurance, and to rule out ectopic pregnancy fetus developing outside of the womb. Early fetal anatomy can also be assessed during this scan. For those who can’t wait to find out the gender, this is a non-medical scan no referral required can be performed from 15 weeks. Read more about our Early Gender Scans.
Around week 20 of pregnancy, an anatomy scan is performed to rule out abnormalities that can be visualised with ultrasound imaging such as cleft lip, spina bifida, heart defects, and many other abnormalities. It is also used to check that the fetus size is within normal limits and record the location of the placenta. The gender of the fetus can also usually be established during this scan. It is also used to assess the amount of amniotic fluid surrounding the baby and record the position of the placenta.
This is a non-medical scan.
Ultrasound scanning in pregnancy
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. The only way to diagnose Down syndrome or other chromosomal abnormalities is by having a diagnostic test — either a CVS or an amniocentesis — and testing the fetal cells.
These tests are invasive and require a needle to be passed into the maternal abdomen and uterus and therefore carry a small risk of miscarriage. Many patients do not wish to have the diagnostic test because of the small risk of miscarriage and prefer to have the ultrasound screening test, the NT scan, to help them decide if they wish to proceed to testing the fetus.
Unfortunately, while NT combined with the first trimester biochemical blood test is a very accurate screening test available for chromosomal abnormalities, it will not detect all fetuses affected with Down syndrome or other chromosomal abnormalities. Chromosomal abnormalities occur when there is a change in the number or structure of the chromosomes.
Normally we have 46 chromosomes, 23 pairs numbered and a pair of sex chromosomes. Boys have XY and girls have XX. The most common chromosomal abnormality seen at birth is Down syndrome. In Down syndrome, an extra copy of chromosome 21 is present, giving a total of 47 chromosomes. To be certain your NT scan is performed correctly, it is important that you have your scan performed at an accredited practice.

They check your baby’s size and, at the early pregnancy dating scan, help calculate in by the Royal College of Obstetricians and Gynaecologists. It’s also sometimes referred to as the NT (nuchal translucency) 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. Your midwife or doctor will book you a dating scan appointment.
It will usually take place at your local hospital ultrasound department. The person performing the scan is called a sonographer. You may need to have a full bladder for this scan, as this makes the ultrasound image clearer. You can ask your midwife or doctor before the scan if this is the case.
