Common Indications (specific Uses) of Gallium-67 Imaging
- Whole-body survey to localize source of fever in patients with Fever of Unknown Origin (FUO).
- Detection of pulmonary and mediastinal inflammation/infection, especially in the immunocompromised patient.
- Evaluation and follow-up of active lymphocytic or granulomatous inflammatory processes such as sarcoidosis or tuberculosis.
- Diagnosing vertebral osteomyelitis and/or disk space infection where Ga-67 is preferred over labeled leukocytes.
- Diagnosis and follow-up of medical treatment of retroperitoneal fibrosis.
- Evaluation and follow-up of drug-induced pulmonary toxicity (e.g. Bleomycin, Amiodarone)
- Evaluation of patients who are not candidates for WBC scans (WBC count less than 6,000 and/or poor IV access).
Note that all of these conditions are also seen in PET scans using the less common positron-emitting isotope gallium-68, which has the same chemical characteristics as Ga-67. See gallium-68 generator.

Famous quotes containing the words common and/or indications:
“Poetry, at all times, exercises two distinct functions: it may reveal, it may unveil to every eye, the ideal aspects of common things ... or it may actually add to the number of motives poetic and uncommon in themselves, by the imaginative creation of things that are ideal from their very birth.”
—Walter Pater (1839–1894)
“You must labour to acquire that great and uncommon talent of hating with good breeding, and loving with prudence; to make no quarrel irreconcilable by silly and unnecessary indications of anger; and no friendship dangerous, in care it breaks, by a wanton, indiscreet, and unreserved confidence.”
—Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)
