The spectrum of gallium-67 renal activity in patients with no evidence of renal disease.
Thirty-seven gallium-67 images were reviewed retrospectively to determine relative renal gallium activity ( RGA ) in patients with no evidence of renal disease. Twenty-four patients were classified as having no evidence of renal disease (NRD). RGA was identified in 50.0% (12/24) of patients in the NRD group. We conclude that the presence of RGA neither suggests nor rules out renal disease. Altered nonrenal biological factors (such as saturation of iron-binding capacity) may decrease soft-tissue gallium accumulation while activity in the kidney remains unchanged. The latter provides renal images with better signal-to-noise ratio. Current imaging equipment may allow renal visualization in these patients.
