MAG3 Renal Scan

You will be required to be adequately hydrated for the test. Drinking 1-2 litres of water before your procedure. A full bladder is not required for this examination, so please empty as frequently as you need.

A cannula is inserted into a vein, usually in your arm, in preparation for an injection. The injection contains a slightly radioactive tracer that travels to the kidneys via the blood stream. There are no side effects from this tracer, and it contains only a small amount of radiation.

Imaging of the kidneys will commence immediately and continue for 40 minutes. Depending on your clinical indications, a second injection of Lasix may be administered half way through imaging to help kidney drainage.

Our Nuclear Medicine Physician will review the images and issue a report. Once completed, the report will be sent electronically to your referring health professional.
