This treatment is given to help alleviate pain in joints caused by severe arthritis or synovitis.

This treatment involves the injection of a therapeutic radioactive tracer into the affected joint(s). One hour after the doctor gives the injection a picture is taken of the tracer distribution.


  • Bring a list of all medications and supplements you take. This includes vitamins, herbal remedies, and holistic medications.
  • Do not bring children or pregnant women with you to the department. We do not want to expose them to unnecessary radiation.
  • Any of these procedures is subject to change according to the nuclear medicine physician. The duration of the tests is a rough estimate. Please be aware that the time may be lengthened if a scan has to be repeated, if emergency cases are brought to the department or due to unforeseen circumstances.

About the Procedure

  • The procedure takes about two hours.
  • A doctor will briefly explain the test to you and then prepare the injection site and give the injection of a tracer.
  • You will be given a one hour break for the tracer to distribute itself in the joint.
  • A 10 minute picture is taken of the injection site and tracer distribution.
