$^{67}Ga$ scintigraphy has been used in the evaluation of sarcoidosis, particularly for delineating sites of involvement and grading activity. Three patients admitted in SNUH between Jan. 1986 and Jun. 1987 were diagnosed as sarcoidosis after clinical examination and $^{67}Ga$ scintigraphy. $^{67}Ga$ scintigraphy disclosed increased uptake of radioactivity in both hilar region, mediastinum, both lacrimal glands and parotid glands prior to treatment. In one case after prednisolon therapy, there was definit improvement of clinical findings and $^{67}Ga$ scintigraphy was normalized.
