Our specially trained team performs a wide variety of ultrasound examinations. They check that your pregnancy is going as planned with anomaly and growth scans. This involves making a diagnosis from images seen on an ultrasound monitor.  

Your doctor or midwife will explain at what stage in your pregnancy you may have an ultrasound scan. You will usually be referred to the hospital for this type of examination.

Before your ultrasound examination

Please remember to bring your maternity notes (yellow book) with you. If you have any questions before your appointment, please call the number at the top of this page.

Changing or cancelling your appointment

If you need to change or cancel your appointment for any reason, contact the number at the top of the page. Please tell us as soon as possible so we can give your appointment to another patient.

At your ultrasound examination

The examination takes around 20 - 30 minutes. The sonographer (specialist who performs the ultrasound exam):

  • applies ultrasound jelly to your abdomen (tummy). This helps to get a clear picture on the screen
  • checks your baby to check their development
  • takes several measurements of your baby and plots these on a chart
  • enters the report into your maternity notes.

Sometimes it is not possible to get a clear picture due to the way the baby is positioned at the time of your examination.  If this is the case, the sonographer will discuss this with you and may ask you to return on another date for a repeat examination.

Please ask the sonographer at your appointment if you have any questions or if you would like an ultrasound picture of your baby.

The report will be placed in your maternity notes and available for the midwife or doctor who referred you for the scan to discuss the results with you.
