The image obtained from a moving detector is called a scan, while the image obtained from a stationary camera device is called a scintiphotograph.,NCI: An imaging technique that uses a small dose of a radioactive chemical (isotope) called a tracer that can detect sites of cancer growth, trauma, infection or degenerative disorders. The tracer, which is either injected into a vein or swallowed, travels through the bloodstream to the target organ, and emits gamma rays, which are detected by a gamma camera and analyzed by a computer to form an image of the target organ.,MEDLINEPLUS: <p>Nuclear scanning uses radioactive substances to see structures and functions inside your body.
