Nuclear Medicine Imaging

Nuclear Medicine Imaging is a specialized service that uses small amounts of radioactive material (radiopharmaceutical) to diagnose many different diseases. The radiopharmaceutical is usually injected into an arm vein where it then moves to specific organs or tissues. A gamma camera then works with computers to create images and provide information about the area in question.

Unlike X-rays or other radiological tests, Nuclear Medicine imaging can assess the function of an organ, bone or tissue rather than just examine its appearance. This allows us to identify the cause or status of a disease before it’s apparent in other diagnostic tests.


  • 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.
