False colour bone scintigram (gamma camera scan) of a coronal (frontal) view of a normal adult skeleton,showing ribs,thoracic & lumbar spine and pelvis (bottom). Bone scans record the distribution & intensity of gamma radiations emanating from a radionuclide injected into the body prior to taking the scan,which concentrates in bone. A crystal scintillator in the camera resolves radiations as flashes of light that are detected by a system of photomultipliers. Bone scans are used to assess presence & extent of bone cancers,which present as sites of increased radionuclide uptake that appear as brighter,"hot spots" on the image | |
