Using advanced imaging ultrasound systems, Synergy Radiology provides high image quality for medical diagnosis in obstetrics. Our sonographers and specialist radiologists highly trained and experienced in all facets of obstetric imaging. It is important to bring all previous results relating to the region being imaged. Please be on time for your appointment to ensure there is sufficient time available to perform the procedure. To ensure clear images, you will be asked to attend with a full bladder. This is achieved by emptying your bladder 2 hours before your appointment and then immediately drinking ml of water. Do not empty your bladder again before the procedure. You may eat normally and take any necessary medication. The ultrasound waves are transmitted and collected via a hand held probe which is moved over the abdomen. You will not feel any pain or discomfort.
Women’s imaging, including obstetrics
All women will be offered ultrasound scans of their baby at around 12 and 20 weeks. Ultrasound scanning has been used extensively in pregnancy and is accepted to be safe. This scan also measures the baby and estimates how many weeks pregnant you are.
(b) nuchal translucency measurement is performed to assess the risk of fetal abnormality; and fetal development and anatomy, ultrasound scan of, by any or all approaches, (a) the dating for the pregnancy (as confirmed by ultrasound) is 17 to 22 weeks of (iv) has obstetric privileges at a non metropolitan hospital; and.
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. The sonographer will tuck a piece of tissue into your underwear to protect your clothes, then drop some gel onto your abdomen. This helps the scanning head to glide smoothly over your skin to get a clear image.
Most dating scans are done with a trans-abdominal transducer and require a full bladder. However, if the pregnancy is in very early stages, the gestational sac and foetus may not be big enough to visualise and you may be offered an internal, transvaginal TV scan which will result in clearer images. Your image films will be provided to you at the completion of appointment. Nuchal Translucency weeks. Sometime between weeks 12 and 14 of your pregnancy you might be offered a Nuchal translucency scan.
A Nuchal Translucency NT assessment is used to indicate whether a baby has a low or high risk of a chromosomal abnormality. This is a screening test which helps provide an early indicator to your doctor.
Ultrasound scans during 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.
Pregnancy ultrasound scans work better if you come with a full bladder for dating scan, because it estimates when your baby is due (the estimated date of delivery, or EDD). Nuchal Translucency Scan (First trimester combined screening).
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. There is also then a routine scan at 20 weeks. Individual circumstances may dictate that more scans may be offered and a breakdown of what you could receive is detailed below.
This usually takes place at 6 to 10 weeks of pregnancy.
A dating scan may be performed from 6 weeks of pregnancy, with the optimal time being 8 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. Following the dating scan, a Nuchal Translucency NT scan is usually performed around Week 12 of pregnancy but can generally be done between 12 weeks 0 days to 13 weeks 6 days.
The NT scan is a screening test for early detection of Down Syndrome. Early fetal anatomy can also be assessed during this scan. Our sonographers are accredited to perform Nuchal Screening.
A dating scan is an ultrasound scan to determine how many weeks pregnant you are and your due date. Learn RANZCOG – Royal Australian and New Zealand College of Obstetricians and Nuchal Translucency Scan – InsideRadiology.

Pregnancy & nuchal translucency ultrasound
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.
Dating/nuchal scan; Mid trimester anatomy scan; 36 week scan. The Obstetric Ultrasound Department and Fetal Medicine Unit both offer a Consultant-led and.
Unless there are concerns about the pregnancy it is better to wait to have this scan after 7 weeks as the images are clearer for you to see and better for us to measure. If you come before 7 weeks the baby will be less than 1cm in size and so the scan sometimes has to be performed transvaginally placing the probe inside the vagina to enable us to see the baby well enough to measure and to see the heartbeat. We ask that you come with a full bladder for this scan as it usually allows us to get the best possible picture of the baby.
If you decide to go ahead with this optional screening test you will be offered a scan between 12 weeks and 13 weeks 6 days ideally 12 weeks. This is the only time that this scan can be performed. We send these measurements to LabPlus in Auckland where a blood sample from you is also sent. LabPlus then calculate the risk or chance that your pregnancy is affected with Down Syndrome. Because this calculation is not carried out on site we are not able to give you the results straight away on the day.
LabPlus will contact your midwife with the results and she will discuss the results with you. This is a detailed ultrasound scan, usually carried out when you are 20 weeks pregnant. So whilst a normal 20 week scan is very reassuring it cannot guarantee a healthy baby.
Us obstetric nuchal dating scan
Please remember keep your phone on flight mode during the scan. Please do not go to the toilet for the half hour before your appointment. I just wanted to say how wonderful you are! I popped in this morning for my 12 week scan and I was blown away by how you are genuinely enthusiastic and passionate about what you do.
It made my husband, myself and my very excited mother in law reassured that we are and bubs in the best of hands.
The common first step will be a dating scan between weeks as we like to check your baby before 10 weeks. Before 7 weeks it may be too early to acquire this information. To obtain the best images possible, this scan is routinely performed internally and perfectly safe to perform during early pregnancy. At 7 weeks gestation a pregnancy sac should be seen within the uterus. Within this sac will be an embryo, heart motion and yolk sac should be visible.
Approaching 8 weeks, early brain formation is identified with a black space in the head called the rhombencephalon. Sometimes it may be too early to gather all the information required to confirm the stage of your pregnancy.
Ultrasound-Obstetric screening tests
Most pregnant women will have an ultrasound scan during their pregnancy. This simple test is quite safe for both mother and baby and causes only minor, if any, discomfort. Ultrasound is a way of taking a look at the baby without using potentially dangerous X-rays. During an ultrasound scan, high-frequency soundwaves are used to create moving images of the developing baby, shown on a screen.
Ultrasound scans may be recommended at various stages of pregnancy for several reasons. Here are some examples.
Following the dating scan, a screening test for early detection of Down syndrome (called a Nuchal Translucency (NT) scan) is usually booked in around week
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. If you want to visit your own FMF page please click here. Aims of the nuchal scan To date the pregnancy accurately. 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. Some major abnormalities may be visible at this gestation.
However it will still be necessary to have a 20 week anomaly scan.
