Bone Scan

A bone scan involves injecting a small amount of a radioactive substance that attaches to the bones. This scan helps detect, or further examine, bone and joint problems sooner than other imaging studies. Your doctor may order it to look for a variety of bone problems, such as:

  • Areas of abnormal joint activity in inflammatory conditions such as rheumatoid arthritis.
  • Bone metastases (cancer in the bone that has spread from a primary cancer).
  • Fractures and stress fractures.
  • Osteomyelitis (bone infection).


  • Please notify your technologist if there is a chance you may be pregnant, or if you are nursing. If you are pregnant, the exam will need to be postponed. If you are uncertain, a blood test will be required to confirm you are not pregnant prior to starting the exam. This may delay or postpone your appointment if not obtained in advance.
  • It’s important to keep hydrated. You can eat and drink normally, both before the exam and between part one and part two of your appointment.
  • Please let your technologist know if you are claustrophobic prior to your exam.
  • This is a two-part appointment booked on the same day.
  • During part one, we will inject a radioactive material (radiopharmaceutical) into a vein in your arm. Part one will take approximately 10-15 minutes and you may leave the clinic until the time you are scheduled to return for part two. You will be given a specific return time.
  • For part two, you will be asked to return to the clinic about 2-4 hours from the time the injection was administered in part one. Part two will take approximately 45 minutes.
  • Please arrive 15 minutes before each part of your appointment to allow enough time to check in with reception.
  • Bring photo identification and your provincial health card.
  • Wear comfortable clothes.
  • Please do not bring children who require supervision.


  • This is a two-part appointment booked on the same day.
  • The first part of your appointment will take approximately 15 minutes.
  • During part one, we will inject a radioactive material (radiopharmaceutical) into a vein in your arm.
  • Your technologist may take a few images while injecting, or immediately following the injection of, the radiopharmaceutical.
  • For the images, you will be asked to lie on your back on the imaging bed and the gamma camera will be placed over your body.
  • After the injection, the technologist will remind you to drink fluids (e.g., water, juice, pop, coffee, or tea) to make sure you are hydrated. You can urinate as needed, since this can help with the appearance of the images. Urinating is also an important way for your body to remove the radiopharmaceutical.
  • You are free to go about your daily activities in the waiting period between the first and second parts of your appointment; there are no restrictions. This time is needed for the injected radiopharmaceutical to attach to your bones.
  • The second part of your appointment is usually 2-4 hours after part one. Your technologist will let you know when to return.
  • During part two, there is no injection; only imaging will be performed. This will take approximately 45 minutes.
  • During the imaging, please hold as still as you can. You may breathe normally, but movement can blur the images and make them more difficult to interpret. Please let your technologist know if you are not comfortably positioned on the bed.
  • The scan is painless and you will be able to talk to your technologist throughout the procedure.
  • SPECIAL NOTE: Your doctor may have requested a specific imaging type called SPECT/CT, which will be performed towards the end of part two of your bone scan.


Additional X-rays may be performed to help the radiologist with their interpretation of your bone scan. If this is required, they will be done after the bone scan is finished and may take approximately 30 minutes to complete.


We do our best to have the specialized nuclear medicine physician interpret the data and forward the results to your doctor by the next business day. If there is any additional urgency, please inform our team.


This exam is covered under your Alberta Health Care Plan. It is not currently offered at our Saskatchewan clinics.


Please ensure that you bring your requisition with you to your appointment.
