摘要

J-RIME发布了2015年和2020年乳腺X光摄影诊断参考水平(DRL)。修订下一个 DRL 需要更多新的剂量研究。为准备下一次乳腺 X 射线诊断参考水平的修订,本研究调查了日本乳腺癌筛查质量保证中央机构提供的 2019-2023 年机构图像认证平均腺体剂量(AGD)数据,以及迄今为止合格机构的平均值与乳腺 X 射线系统类型之间的关系。计算机放射成像(CR)和平板探测器(FPD)系统的 AGD 分布第 95 百分位值分别为 2.5 mGy 和 2.0 mGy。此外,由于 FPD 系统的普及,AGD 正在下降,预计未来 FPD 系统和 W/Rh 靶件/滤光片系统的进一步普及将降低 AGD。

Data analysis of average glandular dose in mammography toward revision of the diagnostic reference level of Japan.

Diagnostic reference level (DRL) for mammography for 2015 and 2020 has been published by J-RIME. More new dose studies are needed to revise the next DRL. In preparation for the next revision of the DRL for mammography, this study investigated data from the Japan Central Organization on Quality Assurance of Breast Cancer Screening on the mean average glandular dose (AGD) for institutional image accreditation in 2019-2023 and the relationship between the average at eligible institutions to date and the type of breast X-ray system. The 95th percentile values of the AGD distributions for the Computed Radiography (CR) and Flat Panel Detector (FPD) systems were 2.5 mGy and 2.0 mGy, respectively. Moreover, it is assumed that AGD is decreasing due to the spread of FPD systems, and it is expected that the further spread of FPD systems and systems with W/Rh target/filter will reduce AGD in future.
