This review presents basic information on the dosimetric quantities used in medical imaging for reporting patient doses and establishing diagnostic reference levels. The proper use of the radiation protection quantity "effective dose" to compare doses delivered by different radiological procedures and different imaging modalities with its uncertainties and limitations, is summarised. The estimates of population doses required by the European Directive on Basic Safety Standards is commented on. Referrers and radiologists should be familiar with the dose quantities to inform patients about radiation risks and benefits. The application of effective dose on the cumulative doses from recurrent imaging procedures is also discussed. Patient summary: Basic information on the measurement units (dosimetric quantities) used in medical imaging for reporting radiation doses should be understandable to patients. The Working Group on "Dosimetry for imaging in clinical practice" recommended that a brief explanation on the used dosimetric quantities and units included in the examination imaging report, should be available for patients. The use of the quantity "effective dose" to compare doses to which patients are exposed to from different radiological procedures and its uncertainties and limitations, should also be explained in plain language. This is also relevant for the dialog on to the cumulative doses from recurrent imaging procedures. The paper summarises these concepts, including the need to estimate the population doses required by the European Directive on Basic Safety Standards. Referrers and radiologists should be familiar with the dose quantities to inform patients about radiation risks and benefits.
本综述介绍了医学成像中用于报告患者剂量和确定诊断参考水平的剂量学量的基本信息。总结了辐射防护量“有效剂量”在比较不同放射学程序和不同成像方式所给予剂量时的正确使用方法及其不确定性和局限性。对欧洲基本安全标准指令所要求的人群剂量估计进行了评论。转诊医生和放射科医生应熟悉剂量量，以便告知患者辐射风险和益处。还讨论了有效剂量在反复成像程序累积剂量方面的应用。患者总结：医学成像中用于报告辐射剂量的测量单位（剂量学量）的基本信息应让患者能够理解。“临床实践成像剂量学”工作组建议，检查成像报告中应包含对所使用的剂量学量和单位的简要解释，供患者参考。还应以通俗易懂的语言解释使用“有效剂量”来比较患者因不同放射学程序所接受的剂量及其不确定性和局限性。这对于关于反复成像程序累积剂量的讨论也很重要。本文总结了这些概念，包括估计欧洲基本安全标准指令所要求的人群剂量的必要性。转诊医生和放射科医生应熟悉剂量量，以便告知患者辐射风险和益处。
