Glossary Term:


bone scan



an imaging test that gives important information about the bones, including the location of cancer that may have spread to the bones. It uses a small amount of radioactive contrast material (radioisotope) which is given by vein. This material settles in areas of the bone to which the cancer may have spread. The radioactive substance can be seen in pictures as it collects in the problem areas (“hot spots”). See also imaging studies, radioisotope.
