Radiation dosimetry of 18F-flurocholine PET/CT studies in prostate cancer patients

For 18F-fluorocholine PET/CT procedures, about 40% of the ED is contributed by administered 18F-fluorocholine and 60% by the CT scan. The kidneys and liver were the highly exposed organs. Considering the large number of diagnostic procedures oncology patients undergo, radiation dosimetry is important in relation to the stochastic risk of such procedures.
