摘要:
尽管CT检查仅占所有检查的2%,而对于公众诊断性成像的接收剂量,CT却占20%左右。具有10mSy有效剂量的成人腹部检查会增加致癌风险1/2000。儿童对于放射线影响的灵敏度是中年人的10倍多,女孩比男孩更敏感。剂量增加的原因有:CT应用的偏差、使用方便的结果、多层CT的危机、未意识到"非耦合效应"。医护人员要进行很好的培训,要意识到不断涌现的资料及实践中潜在的变化,根据进展修正方案。像进行传统X射线摄影一样,"合理使用低剂量(as low as reasonably achievable,ALARA)"
Abstract:
Despite comprising only 2% of all examinations,CT contributed around 20% of the collective dose to the population from diagnostic imaging.An abdominal examination in an adult with an effective dose of 10mSv has been estimated to increase the lifetime risk of fatal cancer by 1 in 2000.Children are 10 times more sensitive to the effects of radiation than middleaged adults.Girls are more sensitive than boys.Variations in CT practice,ease of using,urgency in multislice CT,unawaring of the "uncoupling effect" in CT may be contributing to increasing in radiation dose.We must train.An awareness of emerging and the implied changes in practice,with revision of protocols to take account of advances.The "as low as reasonably achievable (ALARA)" principle applies just as much to CT as it does to conventional radiography.
