Bone Scan

Your caregiver has requested that you have a bone scan. In this test a very small amount of radioactive material is injected into a vein (intravenously). This radioactive material targets your bones, but the highest concentration occurs at areas of:

  • Injury.

  • Disease.

Your bones can then be scanned by a machine that detects radioactive material. The scanning is painless. The scan can detect bone damage from various causes and will sometimes detect very small defects in bones that ordinary X-rays cannot. It can take up to 4 hours to finish a scan.


  • Allergies.

  • Medicines taken including herbs, eye drops, over-the-counter medicines, and creams.

  • Use of steroids (by mouth or creams).

  • Previous problems with anesthetics.

  • Possibility of pregnancy, if this applies.

  • History of blood clots.

  • History of bleeding or blood problems.

  • Previous surgery.

  • Other health problems.


  • Drink extra fluids for 24 hours prior to the exam.

  • Do not have exams using barium or X-ray contrast medium for 48 hours before the exam.

  • Continue with normal routines regarding food and medicines, or as told by your caregiver.

  • Do not wear jewelry or clothes with metal to the exam.


You should be present 60 minutes prior to your procedure or as directed.


  • Radioactive material is injected intravenously over approximately 10 minutes.

  • There generally are no side effects from the injection.

  • Depending on the type of exam, images are taken at varying time intervals for up to 4 hours. Your technologist performing the test will let you know what time intervals will be used for your test. You may go on with normal activities in between scans.


  • Continue drinking extra fluids.

  • Empty your bladder often as this eliminates the radioactive material that your bones do not use.

  • Eat and take medicines normally during the test.


  • You may return to all normal activities.

  • All of the radioactive material will eventually leave your body through your urine. The radioactive material used is in such a small amount you should have no long-term effect from this test.

Your scan will be interpreted by a specialist in reading X-rays (radiologist) with special training in nuclear medicine. He or she will send a report of this scan to your primary caregiver. It may take a couple days for your primary caregiver to receive and review these results. Find out how you are to receive your results, or call for your results as instructed by your caregiver. Remember, it is your responsibility to obtain the results of your procedure. Do not assume everything is fine because you do not hear from your caregiver.
