  • Title: 67Ga citrate in renal allograft rejection.
    Author: George EA, Codd JE, Newton WT, Donati RM.
    Journal: Radiology; 1975 Dec; 117(3 Pt 1):731-3. PubMed ID: 1103231.
    Abstract:
    Eight renal allograft recipients were examined on 31 occasions following administration of 99mTc sulfur colloid and 67Ga citrate. Transplant accumulation of each agent was compared and collated with the clinical diagnosis. The procedures matched in 25 instances (81%). Gallium accumulated in the graft producing a false positive result in 2 instances of acute tubular necrosis with anuria, and failed to accumulate within the graft in one case of chronic rejection and in 2 instances of acute rejection. Both radioagents failed to accumulate in 3 patients with acute rejection following heparin therapy. These data indicate that 99mTc sulfur colloid is superior to 67Ga citrate in establishing the diagnosis of transplant rejection and also provides more timely information.
