摘要
正电子发射计算机断层显像/CT(PET/CT)检查会给受检者带来不可避免的医疗照射,因此辐射剂量的多少成为公众关注的重点问题。PET/CT检查时,受检者要接受来自CT的X射线外照射和放射性药物的内照射。通过对PET/CT辐射剂量的不同影响因素进行分析,可有效指导临床医师对PET/CT检查的必要性进行正确评价。
Positron-emission tomography/CT(PET/CT) examination could bring inevitably medical exposure to patients, so the amount of radiation dose has become an important issue of public concern. In the PET/CT examination, the patients received both external radiation from CT and internal radiation from radiopharmaceutical. The analysis on different influence factors of radiation dose of PET/CT can effectively guide clinicians to implement correct evaluation for the necessity of PET/CT examination.
