St Vincent's Clinic Medical Imaging & Nuclear Medicine


A Leukoscan looks for the presence of infection in the body.

What will happen when you have your Leukoscan

There are two main parts to your leukoscan:

  1. A small injection of a radioactive tracer will be injected into a vein in your arm. This injection is not known to have any side effects but please inform the department if you have had a Leukoscan performed previously. After the injection you will be required to return to the department 2 hours later.
  2. On your return to the Nuclear Medicine department you will be asked to lie on the scanning table and more images will be acquired. This will take approximately 1 hr.

What you need to do and how to prepare for the test

You will not be required to undress for the scan. The scan is performed with the Gamma Camera close to your body but you do not go through a “tunnel”

  • You will need a referral from your doctor
  • You will need an appointment for this test
  • You can eat and drink normally before the test
  • You can take your medications as normal
  • You will be in the department for approximately 30 minutes for the first part of the test and 60 minutes for the second part of the test
  • Please bring any previous relevant X-rays or scans to your appointment
