[Value of gallium-67 scintigraphy in the diagnosis and assessment of activity in sarcoidosis].

Gallium-67 scan has an increased importance in the examination of activity in sarcoidosis. Compared with other markers of activity only gallium-67 can give an information about the localization of active granulomas in the body. It is profitable to distinguish between the accumulation of 67-gallium in the region of hilus and of lung parenchyma. SACE and gallium-67 scan complement each other. There is a good correlation between SACE and gallium-67 score, especially if there is an involvement of lung parenchyma.
