Nuclear Medicine Imaging

Please note, we have temporarily closed nuclear medicine imaging services at our Sunpark clinic.

In Calgary, bone scans and myocardial perfusion imaging (sometimes called a nuclear stress test) are the most common types of nuclear medicine imaging that help diagnose tumours, fractures, arthritis, heart problems, and more.

Nuclear medicine imaging can examine the whole body or a specific area of concern using a small amount of radioactive material (called a radiopharmaceutical) injected into an arm vein that travels through your bloodstream into your bones, or to the heart in the case of myocardial perfusion imaging (MPI). A gamma camera detects the radiation emitted from your body, which is put together by a computer that creates images of the areas of concern.

Areas that take up little or no amount of the radiopharmaceutical appear as "cold" spots, and could show a lack of blood supply to the bone. Areas which take up more radiopharmaceutical show up as "hot" spots, indicating increased blood flow or bone turnover, and could point to problems like arthritis, a tumour, a fracture, or an infection. During MPI, areas of the heart with good blood flow will take up the radiopharmaceutical. Areas which have poor blood flow or have been damaged by a heart attack will take up very little or no radiopharmaceutical.

We offer nuclear medicine imaging at five locations which feature the very latest in state-of-the-art technology.

  • Because a radiopharmaceutical is injected into your body, please notify your technologist if there is a chance you may be pregnant, or if you are nursing. The exam may need to be postponed if you are pregnant or are unsure about your pregnancy status. If you are nursing, you will be given further instructions regarding breastfeeding.
  • Allergic reactions to the tracer are extremely rare, but it is still important to tell your doctor if you have a history of allergies or if you are currently taking medication.
