67Ga-gallium citrate imaging has been found to be a very useful diagnostic modality for the detection and localization of inflammatory lesions. Prior selection of patients who are going to be benefited by this diagnostic procedure is important because of the lack of specificity of this radiopharmaceutical. 67Ga is known to become localized in cerebral infarctions, myocardial infarctions, fracture, Paget's disease of bone, inflammatory and neoplastic processes, and a host of other entities. Hence the need for a better definition and its indications in certain clinical conditions. FUO in the postoperative period and the immunologically deficient patient constitute important situations in addition to the numerous other conditions in which the index of suspicion for an occult septic process is high. In this communication a catalog of inflammatory diseases in various locations is described in which 67Ga imaging is useful.
