摘要

目的: 本研究的目的是为瑞士的乳腺放射摄影提出诊断参考水平(DRLs)值。 方法: 为了收集数据,我们对足够数量的中心进行了调查,其中包括 5 家大学医院、几家州立医院和大型私人诊所,涵盖瑞士所有语言地区,以代表临床实践。收集的数据包括平均腺体剂量(MGD)、压缩乳房厚度(CBT)、乳腺 X 射线摄影模型和每次采集的检查参数。收集的数据分为以下几类:二维或数字乳腺断层合成(DBT)检查、颅尾投影(CC)或内外侧斜投影(MLO),以及 8 类压缩乳腺厚度(CBT),从 20 毫米到 100 毫米不等,间隔为 10 毫米。分析表明,这些数据反映了瑞士的实际情况。结果显示,在相同的 CBT 下,DBT 的 MGD 要大于 2D 采集的 MGD。从 20-30mm 到 90-100mm 的 CBT,2D CC 采集的 MGD 值的第 75 百分位数从 0.81mGy 增加到 2.55mGy,2D MLO 采集的 MGD 值从 0.83mGy 增加到 2.96mGy,DBT CC 采集的 MGD 值从 1.22mGy 增加到 3.66mGy,从 1.33mGy 增加到 4.04mGy。结论: 调查结果使我们能够根据检查类型(2D/DBT)、投影(CC/MLO)和 CBT 为乳腺 X 射线摄影提出瑞士 DRL。与其他研究相比,建议值非常令人满意。

Proposed DRLs for mammography in Switzerland.

The aim of this study is to propose diagnostic reference levels (DRLs) values for mammography in Switzerland. For the data collection, a survey was conducted among a sufficient number of centres, including five University hospitals, several cantonal hospitals, and large private clinics, covering all linguistic regions of Switzerland to be representative of the clinical practice. The data gathered contained the mean glandular dose (MGD), the compressed breast thickness (CBT), the mammography model and the examination parameters for each acquisition. The data collected was sorted into the following categories: 2D or digital breast tomosynthesis (DBT) examination, craniocaudal (CC) or mediolateral oblique (MLO) projection, and eight categories of CBT ranging from 20 mm to 100 mm in 10 mm intervals. A total of 24 762 acquisitions were gathered in 31 centres on 36 mammography units from six manufacturers. The analysis showed that the data reflects the practice in Switzerland. The results revealed that the MGD is larger for DBT than for 2D acquisitions for the same CBT. From 20-30 mm to 90-100 mm of CBT, the 75th percentile of the MGD values obtained increased from 0.81 mGy to 2.55 mGy for 2D CC acquisitions, from 0.83 mGy to 2.96 mGy for 2D MLO acquisitions, from 1.22 mGy to 3.66 mGy for DBT CC acquisitions and from 1.33 mGy to 4.04 mGy for DBT MLO acquisitions. The results of the survey allow us to propose Swiss DRLs for mammography according to the examination type (2D/DBT), projection (CC/MLO) and CBT. The proposed values are very satisfactory in comparison with other studies.

期刊介绍: Journal of Radiological Protection publishes articles on all aspects of radiological protection, including non-ionising as well as ionising radiations. Fields of interest range from research, development and theory to operational matters, education and training. The very wide spectrum of its topics includes: dosimetry, instrument development, specialized measuring techniques, epidemiology, biological effects (in vivo and in vitro) and risk and environmental impact assessments. The journal encourages publication of data and code as well as results.
