Abstract

Background

Previous paediatric diagnostic reference levels (PDRL) literature reviews for commonly performed procedures of the brain, chest and abdomen revealed wide DRL variation and deviation of scanning protocols across CT centres. The current review went further to determine the extent and possible factors of DRL variation in the same procedure, age or weight group, between scanners and CT centres for the standardisation of CT practice globally.

Methods

The preferred reporting items for systematic reviews and meta-analysis (PRISMA) flow chart was used to screen articles in Science Direct, Medline, Academic Search Complete via EBSCOhost, PubMed, and CINAHL via EBSCOhost including the Google search engine.

Results

A total of 6573 articles were retrieved and screened against the established criteria and finally, 52 articles were selected and synthesised narratively.

Conclusion

The findings of this review show variation of brain PDRLs up to a factor of 2 fold for the same examination and age group. Factors attributable to dose variations noted in this review were largely related to the setting of the scan protocols such as the use of different phantom sizes, dose parameters, and age groups. This indicates the need to standardise methods of establishing PDRLs and alignment with the European Commission and ICRP recommended guidelines are proposed.

Implication for practice

The review highlights different methods for establishing PDRLs and their implication which could guide radiographers and medical physicists in future PDRLs establishment for dose optimization.

常见计算机断层扫描程序的儿科诊断参考水平：系统综述。

背景：以往针对脑部、胸部和腹部常见手术的儿科诊断参考水平（PDRL）文献综述显示，各 CT 中心的 DRL 差异很大，扫描方案也存在偏差。目前的综述进一步确定了扫描仪和 CT 中心之间在相同程序、年龄或体重组别中 DRL 差异的程度和可能因素，以实现全球 CT 实践的标准化：方法：采用系统综述和荟萃分析的首选报告项目（PRISMA）流程图在Science Direct、Medline、通过EBSCOhost进行的Academic Search Complete、PubMed和通过EBSCOhost进行的CINAHL（包括谷歌搜索引擎）中筛选文章：结果：共检索到 6573 篇文章，并根据既定标准进行了筛选，最后选出 52 篇文章并进行了叙述性综合：本综述的结果表明，在相同的检查和年龄组中，大脑 PDRLs 的变化可达 2 倍。本综述中指出的导致剂量差异的因素主要与扫描方案的设置有关，如使用不同的模型尺寸、剂量参数和年龄组。这表明有必要将确定 PDRL 的方法标准化，并建议与欧盟委员会和国际放射防护委员会推荐的准则保持一致：本综述强调了建立 PDRL 的不同方法及其影响，可指导放射技师和医学物理学家在未来建立 PDRL 以优化剂量。
