Comparison of split renal function measured by 99mTc-DTPA, 99mTc-MAG3 and 99mTc-DMSA renal scintigraphies in paediatric age groups

Abstract

Currently, in calculation of total and split renal functions (SRF), radionuclide methods are routinely used. We aimed to investigate whether any difference exists betweenSRF values obtained by 99mTc-MAG3, 99mTc-DTPA and 99mTc-DMSA renal scintigraphies. Retrospectively, 38 patients were included in this study. In Group 1, both 99mTc-DTPA and 99mTc-DMSA renal scintigraphies were performed. In Group 2, 99mTc-MAG3 and 99mTc-DMSA renal scintigraphies were performed. SRF were calculated by each method and statistically compared with each other. There was no statistically significant difference between SRF values obtained from 99mTc-DTPA,99mTc-MAG3, and 99mTc-DMSA scintigraphies in 1st and 2nd Group. 99mTc-DTPA,99mTc-MAG3, and 99mTc-DMSA renal scintigraphies give similar SRF measures which may allow use of either of these techniques for calculating the SRF.   Key words: Kidney split renal function, 99mTc-DTPA, 99mTc-MAG3, 99mTc-DMSA.
