A multidisciplinary working group led by the Swiss Federal Office of Public Health was formed to plan and perform a nationwide survey of patient radiation exposure from computed tomography (CT) in hybrid devices across Nuclear Medicine departments. The survey included 16 departments (of which 5 were university hospitals) and the submitted responses included 10,673 entries for the 33 different protocols proposed (11 in PET and 22 in SPECT). The working group determined the selection and exclusion criteria applied to the analysis. This work presents the survey preparation and data analysis including the exclusion criteria used. The results are used to inform recommendations for National Diagnostic Reference Levels (DRL) for CT procedures in Nuclear Medicine in Switzerland. Of the 33 protocols initially proposed, 10 protocols for both PET and SPECT modalities were retained after exclusion criteria and thresholds were applied. The results obtained in terms of volume-weighted computed tomography dose index (CTDI) and dose length product (DLP) have been put forward as recommendations for national Diagnostic Reference Levels for protocols in hybrid imaging devices in Nuclear Medicine in Switzerland and will be published by the Federal Office of Public Health.
由瑞士联邦公共卫生办公室牵头成立了一个多学科工作组，旨在规划并开展一项针对全国范围内核医学部门混合设备中计算机断层扫描（CT）所致患者辐射暴露情况的调查。该调查涵盖了16个部门（其中5个为大学医院），提交的回复包含针对所提出的33种不同方案（11种PET方案和22种SPECT方案）的10673条记录。工作组确定了应用于分析的选择和排除标准。本文介绍了调查准备及数据分析情况，包括所使用的排除标准。研究结果用于为瑞士核医学CT检查的国家诊断参考水平（DRL）提供建议依据。在最初提出的33种方案中，在应用排除标准和阈值后，保留了PET和SPECT两种模式的10种方案。就体积加权计算机断层扫描剂量指数（CTDI）和剂量长度乘积（DLP）所获得的结果，已被作为瑞士核医学混合成像设备方案国家诊断参考水平的建议提出，并将由联邦公共卫生办公室发布。
