GA-67 SCANNING IN SJOGRENS SYNDROME - CONCISE COMMUNICATION

Ga-67 scans were performed in 12 patients with primary or secondary Sjogren''s syndrome (SS). Salivary gland uptake of Ga-67 was noted in 4 of 5 patients with primary SS. Pulmonary uptake was observed in 10 of 12 patients. Chest radiographs were essentially normal in all patients, although 60% complained of significant dyspnea with exertion. The Ga-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.
