Gallium-67 scanning in Sjögren's syndrome: concise communication.
We performed gallium-67 scans in 12 patients with primary or secondary Sjögren's syndrome (SS). Salivary-gland uptake of gallium-67 was noted in four of five patients with primary SS. Pulmonary uptake was observed in ten of 12 patients. Chest radiographs were essentially normal in all patients, although 60% complained of significant dyspnea with exertion. The gallium-67 scan may prove to be a sensitive noninvasive diagnostic test for lung and mediastinal involvement by either primary or secondary SS, and for salivary-gland involvement in primary SS.
