Most scans are carried out by specially trained staff called sonographers. The procedure is carried out in a dimly lit room so the sonographer is able to get good images of your baby. You will first be asked to lie on a couch. You will then be asked to lower your skirt or trousers to your hips and raise your top to your chest. The sonographer will put ultrasound gel on your tummy and tuck tissue paper around your clothing to protect it from the gel.
The gel makes sure there is good contact between the machine and your skin. The sonographer passes a handheld device called a probe over your skin. A black and white picture of the baby will appear on the ultrasound screen. During the examination, sonographers need to keep the screen in a position that gives them a good view of the baby — either directly facing them or at an angle.
The sonographer will carefully examine your baby's body. Having the scan does not hurt, but the sonographer may need to apply slight pressure to get the best views of the baby. However, the sonographer may not be able to get good views if your baby is lying in an awkward position or moving around a lot. If it is difficult to get a good image, the scan may take longer or have to be repeated at another time.
There are no known risks to the baby or the mother from having an ultrasound scan, but it is important that you consider carefully whether to have the scan or not. The scan can provide information that may mean you have to make further important decisions. For example, you may be offered further tests that have a risk of miscarriage. The first scan is sometimes called the dating scan. The sonographer estimates when your baby is due the estimated date of delivery, or EDD based on the baby's measurements.
The dating scan can include a nuchal translucency NT scan, which is part of the combined screening test for Down's syndrome. This scan checks for structural abnormalities anomalies in the baby. Some women may be offered more than two scans, depending on their health and their pregnancy. No, not if you don't want to.
The dating scan and anomaly scan are offered to all women, but you don't have to accept them. Your choice will be respected if you decide not to have the scans, and your antenatal care will continue as normal. You'll be given the chance to discuss it with your maternity team before making your decision. Ultrasound scans can sometimes find problems with the baby.
You may like someone to come with you to the scan appointment. Most hospitals do not allow children to attend scans as childcare is not usually available. Please ask you hospital about this before your appointment. Remember, an ultrasound scan is an important medical examination and it is treated in the same way as any other hospital investigation. Most scans show that the baby is developing normally and no problems are found.
This is because most babies are healthy and do not have abnormalities. Choose the right service. Work out your due date. Make your birth plan.

The screening test for Down's syndrome used at this stage of pregnancy is called the combined test. The combined test involves a blood test and measuring the fluid at the back of the baby's neck nuchal translucency with an ultrasound scan. This is sometimes called a nuchal translucency scan. The nuchal translucency measurement can be taken during the dating scan. If you have agreed to have screening for Down's syndrome, the dating scan and the screening will usually happen at the same time.
Find out more about the combined screening test for Down's syndrome. You will not be offered the combined screening test if your dating scan happens after 14 weeks.
