Abstract:

Relation to high absorption fraction of Tc sestamibi by kidneys in heart scan and these organs are near to generation organs (Ovaries and uterus). Urinary system (kidneys and urinary bladder) are specified as sources organs. The main object of this study is to determine the absorbed dose in these critical organs. we have set amount of absorbed fraction radiopharmaceutical in position of kidneys and Urinary bladder in Rando phantom in form of elliptical surfaces, then absorbed dose to ovaries and uterus measured by TLD-100 that had set at position of these organs in Rando phantom. Results from ORNL phantom MIRD calculation TLD measurement and Rando phantom simulation (MCNP) are comprised. The absorbed dose to uterus and ovaries from urinary system for Rest are 0.139, 0.242 μSv/MBq and for Stress state are 0.105, 0.182 μSv/MBq, respectively.
