Gallium Scan – WR Pediatric Imaging Procedure

What is a gallium scan?
A Gallium Scan is a diagnostic imaging procedure that is used to detect certain cancers and infections.

Why would my doctor request a gallium scan?
A Gallium Scan can help detect or monitor:

  • Lymphoma
  • Infection
  • Osteosarcoma
  • Ewings sarcoma
  • Rhabdomyosarcoma
  • Soft tissue sarcoma

How to prepare for a gallium scan?
There is no preparation needed for this test. You/your child should wear something comfortable and eat breakfast the morning of the scan due to the lengthy imaging time of 2 to 3 hours. Your child may bring a security blanket/toy with him/her to hold during the procedure. You/your child will need to remain as still as possible during imaging to allow for the best quality images.

How is a gallium scan performed?
You will be greeted by one of our technologists who will explain to you/your child what will happen during the examination. The first appointment is for the injection only. A small amount of a radiopharmaceutical called Gallium-67 will be injected into one of your/your child’s veins. When the injection is complete you are free to leave. The technologist will confirm your scan day and time; it is typically two to three days after the injection. The second appointment is the imaging itself. You/your child will be asked to void immediately prior to imaging. Imaging can take anywhere from 2 to 3 hours. Upon completion, the technologist will inform you if a follow-up imaging appointment is necessary to observe bowel clearance.

What can be expected during the procedure?
You/your child may experience some discomfort associated with the insertion of the intravenous needle. The needle used for the procedure is small. Once the radiopharmaceutical is injected, the needle is withdrawn and a gauze bandage with adhesive tape is placed over the site of the injection. The area where the injection was given may be a little sore.

Although the camera may appear large and intimidating, it does not touch you/your child.

What happens after the study?
Once the study is complete, it will be evaluated for quality. If there was too much motion, the study may need to be repeated. If there was no motion, you/your child will be free to leave and resume normal activity.
