  • Title: Calculation of relative glomerular filtration rate and correlation with delayed technetium-99m DMSA imaging.
    Author: Taylor A, Kipper M, Witztum K.
    Journal: Clin Nucl Med; 1986 Jan; 11(1):28-31. PubMed ID: 3002699.
    Abstract:
    The relative renal uptake of Tc-99m DMSA was compared with the relative glomerular filtration rate (GFR) in ten patients with serum creatinines ranging from 0.3 to 2.5 mg/dl. Relative GFR was based on the renal uptake of Tc-99m DTPA determined by two methods: 1) integrating the counts from 1 to 3 minutes postinjection and correcting for background. 2) Totalizing the individual renal counts in a single 15-second frame from 2:45 minutes to 3:00 minutes postinjection and correcting for background. The two methods of determining relative DTPA uptake showed excellent correlation, r = 0.98. Relative DMSA uptake determined at 24 hours post-injection using computer-assisted regions of interest showed excellent correlation with the relative GFR determined by either the integral or single-frame method, r = 0.98. The addition of background subtraction for the DMSA images at 24 hours did not improve the correlation.
