  • No special preparation is required on your part before a bone scan, though you may be asked to remove jewelry or other metal objects.
  • Make sure the patient or a family member has signed a consent form.
  • Because the patient is required to drink 4 to 6 glasses of water or tea in the interval between injection of the tracer and the actual scanning, advise him not to drink large amounts of fluids before the test.
  • You can eat or drink anything you like before the test.
  • After the patient receives an I.V. injection of the tracer and imaging agent, encourage him to increase his intake of fluids for the next 1 to 3 hours to facilitate renal clearance of the circulating free tracer.

  • Bone mineral tracer, 3-ml syringe, 21G needle, 70% povidoneiodine solution, sterile sponge, tourniquet, scanning camera.

What the risks are?

  • If you are pregnant or nursing, the test may be postponed to prevent exposing the fetus to radiation.
  • Occasionally, some soreness or swelling may develop at the injection site.
  • A person may develop rash, or anaphylaxis.
  • There is a slight risk of infection or bleeding with any intravenous injection.
  • Some pediatric experts believe that the radiation used in a bone scan is too high for children, so they recommend a bone scan only when one is absolutely necessary.
