Abstract
Renal scintigraphy plays an important role in the diagnosis of various kidney disorders. This procedure can be performed with different radiopharmaceuticals. The patients undergoing renal scintigraphy receive a radiation dose that should be assessed. In this study, the effective dose of patients due to renal scintigraphy with 99mTc (DMSA, DTPA, EC and MAG3) was calculated for the International Commission on Radiological Protection (ICRP) 110 adult reference phantoms using the Medical Internal Radiation Dose method and the ICRP 60 and 103 tissue weighting factors. The results show that the highest effective dose per unit activity administered is due to 99mTc DMSA. On average, the effective dose per unit activity administered of 99mTc DMSA is almost twice the effective dose per unit activity administered of other radiopharmaceuticals. The effective doses per unit activity administered calculated using the ICRP 103 tissue weighting factors are always lower than that calculated using the ICRP 60 tissue weighting factors and the ICRP 128 data.
