Comparison of Different Equations with GFR Measured by Scintigraphy in Kidney Donors.

Background: Technetium-99 diethylene-triamine-pentaacetate (99Tc-DTPA)-based scintigraphy is a convenient way to assess measured glomerular filtration rate (mGFR) in kidney donors. Equations have been developed to calculate GFR in the general population. This study aims to identify the best among commonly employed equations to better predict GFR when compared with scintigraphy-based mGFR.
