The positron emitters (F-Sodium Fluoride (NaF)) and X-rays used in Positron emission tomography (PET) combined with computed tomography (PET/CT) imaging have a high radiation dose, which results in a high patient dose. The present research intends to determine the radiation dose and risks associated with PET/CT- 18F-Sodium fluoride examinations in patients. The 18F-NaF PET/CT was used to investigate the doses of 86 patients. Patient exposure parameters and ImPACT software were used to calculate mean effective doses. The administered activity of 185 MBq (5.0 mCi) per procedure has a mean and range based on the patient's BMI (BMI). The range of patient effective doses per procedure was found to be 4-10 mSv, with a radiation risk of 1 × 10 per procedure. Patient doses are determined by the patient's size, scanner type, imaging protocol, and reconstruction method. For further dose reduction, proper justification and radiation dose optimization is required.
正电子发射体（F-氟化钠（NaF））和 X 射线在正电子发射断层扫描（PET）与计算机断层扫描（PET/CT）成像中联合使用，辐射剂量很高，导致患者的剂量很高。本研究旨在确定与 18F-氟化钠 PET/CT 检查相关的辐射剂量和风险。使用 18F-NaF PET/CT 研究了 86 名患者的剂量。患者暴露参数和 ImPACT 软件用于计算平均有效剂量。根据患者的 BMI（体重指数），每次检查的 185MBq（5.0mCi）给药活动具有平均值和范围。每次检查的患者有效剂量范围为 4-10mSv，每次检查的辐射风险为 1×10。患者剂量取决于患者的体型、扫描仪类型、成像协议和重建方法。为了进一步降低剂量，需要进行适当的论证和辐射剂量优化。
