In this section
All women will be offered ultrasound scans of their baby at around 12 and 20 weeks. Some women will need extra scans later in the pregnancy for several reasons, such as checking the baby’s growth. Ultrasound scanning has been used extensively in pregnancy and is accepted to be safe. Prior to attending, please try to have a full bladder by drinking 1-2 pints of water/squash about 1 hour before your scan time.
One adult can accompany you in the scan room. Children are not invited to attend the scans. This is to help facilitate concentration of the sonographer as they perform your examination.
Dating scan at around 12 weeks
This is a basic scan to check your baby’s heartbeat and development. This scan also measures the baby and estimates how many weeks pregnant you are. The dates obtained from the scan will be used to calculate your baby’s due date (also known as the Estimated Date of Delivery – EDD).
Nuchal scan
This scan is carried out between 11+2 weeks and 14+1 weeks and measures the amount of fluid lying under the skin at the back of your baby’s neck and combines this result with results from blood samples, your age, weight, weeks of pregnancy, family origin and whether you smoke into a computer programme at the laboratory to work out the risk (chance) figure for Down’s Syndrome, Edwards syndrome and Patau’s syndrome.
Structural (anomaly) scan (18+6 to 20 weeks)
This is a screening test that checks for possible physical problems with your baby. The test is offered to all women, but not everyone will choose to have it. If you choose not to have this scan your choice will be respected and you will be offered a later pregnancy management scan.
This scan is a positive experience for most people, but not for everybody as unfortunately sometimes we find a problem with a baby’s development. Whilst this scan is good at detecting most serious problems, it cannot pick up all possible problems with the baby. For example, only about 60% of heart problems are found. The sonographer will have the screen in a position to give them the best view of the baby. The sonographer will need to concentrate during the scan but will explain the scan findings at the end. The length of the scan varies, but it can take up to 30 minutes depending on your baby’s position.
Scans are not guaranteed to find all problems with a baby. If we do find a problem with the baby or if the scan findings are unclear, we will arrange for you to speak to a doctor and another scan may be arranged. This may be on a different day. In a small number of cases, babies are born with abnormalities that were not spotted on scan. Further information on what we can or can’t see on an ultrasound can be found here.
As this is a medical examination, we will only look and try to see the sex of your baby if asked. We can never be 100% certain and this is not the priority of the scan. Checking the sex of your baby is not possible on some scans.
Scan photos are sold at £3 each or £5 for two.
Growth scan
This is a scan done later in the pregnancy (usually after 26 weeks) to assess your baby’s size. These are not done routinely. If you have had certain problems in a previous pregnancy, then you will be assessed to see if any scans are required. There may also be other clinical reasons why you may require a growth scan, and this will be discussed with you by the midwives and doctors.
