Comparison of DTPA and MAG3 renal scintigraphies in terms of differential renal function based on DMSA renal scintigraphy

Abstract

Objective: Renal scintigraphy has privileges in imaging methods in terms of providing functional information. Technetium-99m dimercaptosuccinic acid (Tc-99m DMSA) used in imaging of renal parenchyma is the most reliable radiopharmaceutical in the calculation of differential renal function (DRF). In this study, it was aimed to compare the agents of dynamic renal scintigraphy such as Technetium-99m diethylenetriamine pentaacetic acid (Tc-99m DTPA) and Technetium-99m mercaptoacethyltriglycine (Tc-99m MAG3) based on Tc-99m DMSA in terms of DRF.
Methodology: Tc-99m DTPA and Tc-99m DMSA scintigraphies were performed in Group A; Tc-99m MAG3 and Tc-99m DMSA scintigraphies were performed in Group B. There were 57 patients [23 F, 34 M; mean age: 18.8
