A patient is prepared for a PET scan with an injection of slightly radioactive material, typically tagging molecules that behave like glucose within the body. Since cancerous tissues consume glucose, the scanner can then detect their location. PET technology can also be employed in the diagnosis of cardiovascular disease and Alzheimer's disease.
