Changes in results of Gallium-67-citrate scanning after interferon therapy for chronic hepatitis C.

Abstract

IFN caused uptake of the radionuclide to increase in most patients. This method showed changes in the accumulation of 67Ga-citrate that could have been missed if the results had been inspected by eye. IFN can cause interstitial lung disease, but unlike other drugs with this side effect, the onset seems to be gradual enough to be detected quantitatively by 67Ga scanning.
