Answer

Radionuclide scans (ie, technetium-99m [99m Tc], gallium-67 [67 Ga], indium-111 [111 In] leukocyte scans) are used to nonspecifically localize areas of inflammation. They cannot be used to distinguish infectious from sterile processes. However, radionuclide scans may be of use in diagnosing septic arthritis in relatively sequestered areas, such as the hip and sacroiliac joints.
