You have been referred for a Gallium-67 Study (or Gallium Scan) in which imaging is done 48 hours after a small injection of tracer.
A Gallium Scan is sensitive in showing up tumors, inflammation, osteomyelitis involving the spine, imaging older and chronic infections that may be the cause of a fever of unknown origin (PUO).
The test involves a small injection of “tracer” (like having a blood test).
The tracer used is called Gallium-67 Citrate. There are rarely any side effects with this injection.
Images are done 48 hours after the injection, of the area causing you problems. This is done using a Gamma Camera (1) and usually takes 30 minutes.
Often, we require to image the problem area in 3D 'after' reviewing the first images. This is called SPECT/CT (2) imaging.
With SPECT/CT imaging, the same Gamma Camera simply rotates around your body, taking images all the time. This can take 15-30 minutes.
You receive a slight radiation dose by having a Gallium Scan with SPECT/CT ~ up to 9.2 times your yearly background radiation (3).
If you are pregnant, trying to fall pregnant or breast feeding, you must inform our staff.
If you have had prior imaging e.g. PET, Nuclear Scan, CT, MRI, X-Ray, Ultrasound, etc... please bring these with you.
Please also bring your referral and any blood results that you may have had done.
There is no preparation for a Gallium Scan i.e. eat and drink as normal.
If you are on any medications, please take these as normal.
Wear comfortable clothing and minimise the amount of metal jewellery you have on (all metal objects will need to be removed prior to imaging).
Important Note: You cannot have this test if you have had a PET or Nuclear Scan within 24 hours prior to this test. If you have had Iodine-131 therapy, allow 4-weeks before having this test. Please ring to discuss booking options.
Breast-Feeding Mothers: Once you have been given the tracer, you need to stop breast-feeding for 20-days. During the first 3-days, you need to express and discard your breast milk as often as required. You will need to bottle-feed your child during this 20-day period. Before starting breast-feeding again, express and discard your breast milk one last time.
(1) A Gamma Camera is a device that detects gamma-rays (gamma-rays are very similar to x-rays) and does not emit any radiation.
(2) SPECT/CT imaging (Single Photon Emission Computer Tomography / Computer Tomography). CT does emit radiation
(3) We all receive a yearly background radiation dose ~ 2.4mSv. Gallium Scan with SPECT/CT ~ 22mSv = 9.2 times yearly background dose.
