  • Title: Technetium-99m DMSA imaging and the obstructed kidney.
    Author: Piepsz A, Ham HR, Roland JH, Froideville JL, Kinthaert J, Hall M, Verboven M, Collier F.
    Journal: Clin Nucl Med; 1986 Jun; 11(6):389-91. PubMed ID: 3013481.
    Abstract:
    Although several authors have claimed that the function of an obstructed kidney could be overestimated on Tc-99m DMSA imaging, the clinical importance of such an overestimation has not been well documented. Partial obstruction of one ureter was created in a rat, and a relative Tc-99m DMSA uptake was obtained 4 hours after intravenous injection. By puncture of the isolated obstructed kidney, it was shown that the function of that kidney was overestimated by at least 17%.
