The use of CT in the US has been increasing exponentially over the past decade. The greatest increases in CT use have been in pediatric diagnosis and adult screening. Unfortunately, there is little cognizance among health-care providers (or their patients) about the relative latent cancer risks associated with repetitive exposure to ionizing radiation. Given the exposure of a relatively high proportion of the population to these tests, it is incumbent on health-care providers to have an improved understanding of these risks and discuss them accordingly with their patients. The risks and benefits of these tests should be carefully analyzed and radiation exposure risk assessment should be conducted as part of the selection of diagnostic and screening tests. Appropriate discussion between physicians and patients of the risks associated with radiographic studies is warranted to inform patients of the longitudinal risks of subsequent testing.
在过去的十年中，美国的 CT 使用呈指数级增长。CT 使用的最大增长是在儿科诊断和成人筛查方面。不幸的是，医疗保健提供者（或其患者）对与重复接触电离辐射相关的相对潜在癌症风险几乎没有认识。鉴于相对较高比例的人口接受这些测试，医疗保健提供者有责任更好地了解这些风险，并相应地与他们的患者讨论这些风险。这些测试的风险和益处应仔细分析，并应进行辐射暴露风险评估，作为选择诊断和筛查测试的一部分。医生和患者之间应就放射学研究相关的风险进行适当讨论，以使患者了解后续检查的纵向风险。
