Nuclear medicine
Nuclear medicine is a branch of medicine that uses radioactive materials to investigate how different parts of the body work. The radioactive material (called a radiopharmaceutical or tracer) is administered to the patient and the areas where it settles are imaged using a special machine called a gamma camera.
As well as detecting abnormalities in the body, some radiopharmaceuticals can be used to treat disease.
