Gallium-67 Scintigraphy is used for two broad purposes: The first is to detect infection. The scan is particularly useful in detecting infection or inflammation in the spine, chest region and is also useful to investigate suspected infection in bones and joints of other regions. Interpretation of the scan in the abdomen region, however, may be difficult at times since Gallium-67 is also normally secreted from the blood into the bowel progressively after several hours. The second purpose of this scan is to demonstrate cancers known as lymphomas, particularly non-Hodgkin’s lymphoma and Hodgkin’s disease.
