The findings of gallium imaging suggest that parotid abnormalities in sarcoidosis are common. Correlation with lung and mediastinal uptake suggests that this represents an early disease state and that it responds to steroid administration. That the findings after therapy do not simply represent suppression of the uptake mechanism for gallium is supported by objective ...
