Bone scan of legs and feet. Coloured radionuclide bone scan (gamma scan) of a patient's lower legs and feet. The bones are colour-coded blue and yellow. This image was made with a gamma camera, which detects gamma rays emitted by a radioactive tracer that concentrates in bone. The tracer - a phosphate complex linked to the radioactive isotope technetium-99m - is injected into the body before the scan is taken. Bone scans are often used to screen cancer patients for evidence of secondary disease after they have received treatment for their primary cancers.
