comparison of ivp-simulator and 99mtc-dmsa renal scaning for renal localization and shielding in candidates for radiation therapy [persian]

to minimize renal radiation in abdomical radiotherapy, shielding of the kidneys is essential. ivp-simulator is used as an standard method. in this study, we used 99mtc-dmsa to localize and shield the kidneys and we compared this method with ivp-simulator. the size of the kidneys was proven to be larger as compared with ivp method. the mean of the overlap percentage was 81.88 in right and 82.89 in left kidney. the confidence interval between two methods ranged from 20 to 80 percent. it is concluded that this is a useful method and can be recommended for localization and shielding of the kidneys in patients with abdominal radiotherapy.
