  • Nuclear medicine demonstrates both organ function and structure.
  • Small amount of radioactive materials called radiopharmaceuticals are used.
  • These substances are either injected or swallowed. They are designed to be processed by specific organs or concentrate in the bones or soft tissue.
  • A tiny amount of radioactivity is emitted. A Gamma camera can detect these emissions and the data is sent to a computer to form an image.
  • Nuclear medicine studies can detect abnormalities in the early stages of the disease process.
  • Thyroid, gallbladder, stomach, and bone are the most common organs assessed by nuclear medicine. Other types of studies:
