Abstract
Pet/ct with 18f-fdg is increasingly used for diagnostic imaging, making dosimetry evaluation crucial to reduce unnecessary radiation exposure to other organs. This study aimed to compare and evaluate the absorbed dose to patients undergoing 18f-fdg sequential pet/ct imaging in the ikn using olinda/exm and geant4 mc simulation, focusing on identifying the most suitable method for clinical application and analysing whether the absorbed dose comply with the safety standard set by icrp 128. The study involved retrospective analysis on 30 adult patients. Inclusive of 13 men and 17 women with mean age, weight and administered activity were 55.10 ± 14.05 years, 68.87 ± 20.99 kg and 327.61 ± 87.95 mbq respectively. Olinda/exm version 1.1 and geant4 mc simulation (version 10.6.0) software were used to evaluate the absorbed doses to liver, kidney and urinary bladder. Mird5 mathematical phantom were used in geant4 mc simulations whereas in olinda/exm, adults male and female models which the organ mass were normalized with japanese reference model were applied.
