Anomaly Scan

What is an anomaly scan?

The anomaly scan is one of the most important ultrasounds you will have during your pregnancy. It is usually performed at around 20 weeks, when all your baby’s major organs will be visible. We will perform a thorough check for abnormalities, measure your baby’s growth, and make sure the placenta is healthy. If you haven’t already had a sexing scan, then we’ll also be able to tell you if your baby is a boy or girl.

Why this scan?

  • Check for abnormalities
  • Check for abnormalities

What you will receive

  • Detailed scan report for your maternity notes
  • Scan pictures
  • Link to your electronic pictures and video

When Should You Have the Anomaly Scan?

The anomaly scan is recommended for all women at 20-24 weeks of pregnancy. At this stage in your baby’s development it is possible to see detailed pictures of the head, brain, limbs, spine and major organs. We can therefore check that everything is developing as expected and detect any abnormalities. We will also measure your baby so that we can see how much he or she has grown since the last scan and check the cervix, placenta, amniotic fluid and umbilical cord.

The 20 week scan is usually the most detailed health check that we will perform during your pregnancy. Although it can’t detect all kinds of abnormalities, it can provide a lot of information about your baby. It can also be very reassuring to hear that everything is looking good on the scan.

If you haven’t had a scan since the nuchal ultrasound, then you will be able to find out your baby’s gender during the anomaly scan. You will also be able to see how much your baby has grown and changed since your last ultrasound. By 20 weeks your baby is fully formed but only measures about 25cm from head to heel. Babies are already very active at this stage, so you may see him or her moving around during the scan.

What to Expect

  • The anomaly scan is usually performed between 20-24 weeks
  • It is a trans-abdominal scan, so the ultrasound probe will be placed against your belly. You’ll need to pull back your clothing so that we can place the probe against your skin. It is also helpful to have a moderately full bladder, so you should have a drink of water before the scan.
  • In most cases, the results will reassure you that everything is well. If any issues are detected, then you may need further tests or treatment to address them. You will be able to discuss the results with one of our experienced sonographers if you have any concerns.
