Abstract

QUESTION

Does radiation exposure in pediatric CT require a specific action?

METHODS

Review of the recent literature.

RESULTS

Increasing medical applications and numbers of examinations coupled with a significant individual radiation exposure have increased the CT contribution to medical exposure to around 38-60%. An up to 10-fold increase in radiation sensitivity of small children, their longer life expectancy and an overdose due to protocols copied from adult patients are the factors responsible for a small but significant excess of cancer mortality over lifetime. Strict referral and use of the many technical and medical ways of reducing exposure help reduce exposure.

CONCLUSION

Realizing the problem of pediatric CT-exposure is as important as analyzing and reducing the causes of biologic impact by CT.

摘要

问题

儿科CT检查中的辐射暴露是否需要采取特定措施？

方法

回顾近期文献。

结果

随着医疗应用的增加和检查数量的增多，再加上个体辐射暴露显著，CT对医疗辐射暴露的贡献已增至约38% - 60%。幼儿辐射敏感性高达成人的10倍、预期寿命更长以及因照搬成人患者方案导致的过量辐射，这些因素致使终生癌症死亡率虽小幅但显著上升。严格的转诊以及运用多种技术和医疗手段减少辐射有助于降低暴露剂量。
