A type of imaging scan that is used to tell if lung cancer has spread to other parts of the body. For this test, a form of radioactive sugar (known as FDG) is injected into the blood. Because cancer cells in the body are growing quickly, they absorb more of the radioactive sugar. This radioactivity can be seen with a special camera.12
