Will I be able to stay with my child during the scan?
One parent or guardian may stay in the room during the scan, but no other children are allowed.
How is the Lasix scan done?
A nuclear medicine technologist will do the test. They will explain it to your child step by step.
Your child will first have an injection (needle) into their vein to give fluids, a very small amount of radioactive medicine, and medication called Lasix.
The technologist will then gently place a small flexible tube called a catheter in your child's urethra (say: yoo-REETH-ra). The urethra is the opening that allows urine to flow out of the bladder.
The catheter helps keep your child's bladder empty while the camera takes pictures of the kidneys. The radioactive medicine will be clear in the pictures and will show if your child's kidneys are blocked in any way.
Once the scan is done, the technologist will gently remove the catheter.
The technologist will do everything they can to respect your child's privacy and make your child as comfortable as possible during the scan.
Note: The injection before the scan is not painful, but your child's hand or arm can still be numbed first with a topical anaesthetic (a special cream or cooling spray). If you would like this option, it is best to arrive at least 30 minutes before your appointment to allow the anaesthetic to take effect.
