Ga-67 scintigraphy in the differential diagnosis between acute interstitial nephritis and acute tubular necrosis: an experimentaln study

摘要

Background. The differentiation between acute interstitial nephritis (AIN) and acute tubular necrosis (ATN) is crucial in patients with acute kidney injury. Gallium-67 citrate (Ga-67) has been used clinically in the differential diagnosis between these entities, but its efficacy is disputed. The aim of this study was to evaluate Ga-67 scintigraphy efficacy in the differentiation between experimental models of drug-induced AIN and ATN.
