| 摘 要： | PET/CT是临床中不可替代的工具。PET/CT受检者的受照剂量是由PET和CT两部分导致的受照剂量之和。本文通过研究数据论述PET/CT受检者受照水平。PET/CT和其他的放射诊断方法一样，均为所获得的益处高于辐射风险。对受检者受照剂量的夸大及忽视均不可取。在满足临床需求的条件下，应尽量控制受检者的受照剂量。

| Abstract: | Positron emission tomography/computed tomography (PET/CT) scanner is an irreplaceable instrument in clinical diagnosis. The exposure dose that a patient receives is the sum of the doses caused by PET and CT examination. This study discussed the exposure dose level that a patient received during PET/CT examination according to the research data. Like other radiological diagnostic methods, PET/CT examination brings benefits outweighing its radiation risk. It is not advisable to exaggerate or ignore the exposure dose. The patient’s exposure dose caused by PET/CT examination should be controlled as much as possible under the premise of meeting clinical needs. |
