Nuclear medicine is a specialized area of radiology that uses very small amounts of radioactive materials (given either orally or intravenously) to examine an organ’s structure and metabolic function, and is used to:
- Scan organs for abnormalities
- Evaluate the spread of cancer
- Locate infection
- Identify blood clots in the lungs
This creates images of the body using radioactive substances, detecting tumors and determining the quality of blood flow through the heart and lungs.
