Basic Study on the Estimation of Medical Exposure Dose Using Monte Carlo Simulation

Internal radiation dose estimation using multiple D‐shuttle dosimeters for positron emission tomography (PET): A validation study usingNEMAbody phantom

“…1,2 A large amount of radioactivity is administrated for the examinee when acquiring functional information on a patient during a PET examination, although the half-life of the radioactivity is very short. 2,3 Because of the harmful effect of ionizing radiation, a patient's radiation exposure is becoming a concerning issue during PET examinations. 4 Internal radiation dosimetry in nuclear medicine is a very important procedure for balancing the potential risks from radiation exposure during a PET examination against its benefits.…”

“…Positron emission tomography (PET) is an important radioisotope imaging modality in nuclear medicine for the diagnosis, prognosis, staging, treatment response monitoring, and radiation therapy planning for a wide range of malignancies . A large amount of radioactivity is administrated for the examinee when acquiring functional information on a patient during a PET examination, although the half‐life of the radioactivity is very short .
