Abstract

Objectives: 99mTc-MAG3 is a standard radiotracer for renal dynamic functional study. Despite its properties for clinical uses, it has numerous technical limitations. 99mTc-EC is also a tubular radiotracer for renal imaging, which has not been used worldwide. In this study, the use of 99mTc-EC and 99mTc-MAG3 for RENAL FUNCTIONal study were compared.Methods: Thirty five patients (20 male, 15 female; mean age of 34.63 ±10.69 years) were entered in the study. About 10 mCi of 99mTc-EC and 99mTc-MAG3 were administered in different days within 7 days intervals and serial images were obtained for 30 minutes. Serum creatinine and visual scintigraphic findings of all patients were within normal limits.Results: In this study, the renal uptake of 99mTc-EC was significantly higher than 99mTc-MAG3 (6.20% vs 4.39% of the injected dose), while the hepatic activity of 99mTc-EC was significantly lower (307 vs 439 mean pixel count, p<0.0001). Also the absolute values for some other quantitative parameters such as right and left kidney transit times and ERPF were different for each radiotracer. In spite of these differences most quantitative parameters (except for right kidney transit time, liver uptake and Tmax of both kidneys) showed good correlations for both agents.Conclusion: The calculated ERPF with 99mTc-EC as compared to 99mTc-MAG3 is in closer proximity to the true values. Also the use of 99mTc-EC compared to 99mTc-MAG3 in clinic due to simplicity of preparation, higher stability, higher renal uptake, and lower hepatobiliary activity is better. Therefore the use of 99mTc-EC as an appropriate substitute or ever preferred radiopharmaceutical for 99mTc-MAG3 radiopharmaceutical for RENAL FUNCTION studies is recommended.
