Growth scans are typically performed in the third trimester of pregnancy.

The purpose of a growth scan scan is to assess:

  • Overall growth of the baby
  • Position of the placenta
  • The volume of fluid around the baby
  • Limited assessment of the anatomy
  • The blood flow to baby

Use our Pregnancy Scan Calculator to help with the timing of your scans.

Before Your Growth Scan

If possible, please wear comfortable, loose-fitting clothing that allows easy access to the area that is being imaged. Two-piece clothing is ideal (separate upper/lower garments).

Please empty your bladder two hours before the examination time. Then slowly drink 600ml of water to fill your bladder and keep it full for your examination.


When you visit Adelaide Women’s Imaging for a growth scan you will be greeted by one of our friendly reception staff. A sonographer will then collect you from the waiting room and take you to the ultrasound room. The sonographer will perform an ultrasound of the abdomen (transabdominal ultrasound) detailing the fetal anatomy and maternal pelvic anatomy.

The sonographer will begin by asking you to lie on a bed next to the ultrasound machine. A clear gel is applied to your stomach. The ultrasound probe is then placed in contact with the skin and moved over the surface of the lower abdomen to study the baby below. The scan is completely painless, although pressure may be applied to improve view in some areas. The sonographer will take an initial set of images that will be reviewed by the Adelaide Women’s Imaging obstetrician and gynaecologist.

The Adelaide Women’s Imaging doctor will perform a brief ultrasound assessment and discuss the results of the scan with you on the day in the ultrasound room. A detailed report will be sent to your referring doctor.
