Renal allograft rejection:role of Tc99m-DTP a renal scan

ABSTRACT

Objective: Tc99m- diethylene triamine pentaacitic acid [DTP A] renal renography has been used to evaluate renal transplant function with variable results. In this study we compared the results of renal scan with biopsies of renal ailograft to evaluate the ability of renography to differentiate acute rejection from other causes of allograft dysfunction including acute tubular necrosis [ATN] and medication toxicity
