Evaluation of the emphasis of themes pertaining to radiation dose and dose reduction at the Meeting of the German Radiological Society from 1998 - 2008 in comparison to international data.
Retrospective analysis of 9440 abstracts with documentation of study presentation character, type of imaging, and examined body region. Abstracts stating radiation dose or primarily dealing with radiation dose/dose reduction were documented. Results were compared with a Pubmed query.
The percentage of purely scientific presentations sank in the observation period from 88 to 66 %. While contributions dealing with MRI sank from 48 to 34 %, those dealing with CT rose from 30 to 34 %. The percentage of abstracts dealing with radiation dose rose from 7 to 10 %, while that of work primarily pertaining to dose/dose reduction grew from 4 to 6 % and 2 to 4 %, respectively. Of all abstracts concerning CT, 15 % touched on radiation dose, while 9 % and 6 % primarily dealt with dose and dose reduction. The respective numbers for cardiac CT, whose relative share of all CT abstracts rose from 3 % in 1998 to 12 % in 2008, were 10 %, 7 %, and 5 %. An online query produced 137,791 publications on CT, and 2 % of these abstracts mentioned radiation dose and 0.5 % mentioned dose reduction.
The number of presentations dealing with dose at the Meeting of the German Radiological Society has risen with time and is higher than the international number. On the other hand, > 90 % of all presentations and > 85 % of all CT abstracts do not mention radiation dose. In light of increasing public concern relating to radiation exposure, more intensive research of these themes is warranted.
评估1998 - 2008年德国放射学会会议上与辐射剂量和剂量降低相关主题的重点，并与国际数据进行比较。
对9440篇摘要进行回顾性分析，记录研究报告的性质、成像类型和检查的身体部位。记录提及辐射剂量或主要涉及辐射剂量/剂量降低的摘要。将结果与PubMed查询结果进行比较。
在观察期内，纯科学报告的比例从88%降至66%。涉及MRI的报告从48%降至34%，而涉及CT的报告从30%升至34%。涉及辐射剂量的摘要比例从7%升至10%，而主要与剂量/剂量降低相关的工作比例分别从4%升至6%和从2%升至4%。在所有关于CT的摘要中，15%涉及辐射剂量，而9%和6%主要涉及剂量和剂量降低。心脏CT的相应数字分别为10%、7%和5%，其在所有CT摘要中的相对比例从1998年的3%升至2008年的12%。在线查询产生了137791篇关于CT的出版物，其中2%的摘要提及辐射剂量，0.5%提及剂量降低。
德国放射学会会议上涉及剂量的报告数量随时间增加，且高于国际数量。另一方面，所有报告中有>90%以及所有CT摘要中有>85%未提及辐射剂量。鉴于公众对辐射暴露的关注度不断提高，有必要对这些主题进行更深入的研究。
