Skeleton. Coloured gamma scans of a healthy human skeleton seen from the front (left) and back. Gamma scans involve injecting a radioactive isotope into the body. In this case, a radionuclide that accumulates in bone was chosen. The gamma radiation given off by the isotope is detected and converted into these images. Gamma scans can be used to detect bone tumours.
