Information about your ultrasound scan: FAST and FULL BLADDER

exp date isn't null, but text field is


Your doctor has referred your child for an Ultrasound Scan.  This will take place in the Imaging Department (also known as Radiology or X-ray department) on the Ground Floor of the Royal Hospital for Children.

Do I need to do any special preparation before the Ultrasound scan?

  • Your child needs to fast for this scan, which means no eating at all and only drinking water.
  • Your child also needs to have a full bladder for this scan because it acts like a window. The fuller their bladder is the more we can see!
