Gallium citrate Ga 67 has been reported to be of value in the diagnosis of both malignant and infectious intra-abdominal diseases. The drug may also be taken up by mononuclear phagocytes in noninfectious tubulo-interstitial disease of the kidney. Positive renal scans from patients with these diseases either become negative or show decreased uptake following treatment. With further support of these findings, gallium citrate Ga 67 may become a valuable tool in both diagnosis and follow-up of noninfectious interstitial nephritis.
