Abstract

Introduction

The use of contrast-enhanced spectral mammography (CESM) has increased in recent years, as has awareness of radiation dose safety among professionals and patients. The principal aim of this study was to compare radiation exposure measured using the entrance surface dose (ESD) and the average glandular dose (AGD) in CESM, Full-Field Digital Mammography (FFDM) and Digital Breast Tomosynthesis (DBT). Our second objective was to evaluate differences caused by compressed breast thickness, compression force and patient age.

Methods

A retrospective observational study included all patients who had undergone a CESM between May 2021 and May 2022. Data was collected on ESD and AGD from the different CESM studies, and breast density and volume were determined by two expert radiologists. The comparative analysis focused on the dose of radiation received during the craniocaudal (CC) projection of the right breast in CESM studies and FFDM or DBT, performed within a 12-month period. Lastly, a statistical analysis was performed to determine the influence of breast compression thickness, compression force and patient age.

Results

Seventy-seven patients participated in the comparative study and forty-four in the dosimetric study. Differences in radiation dose (ESD/AGD) were found among the three breast imaging techniques. The dose in CESM (1.70/5.39 mGy) was lower than in DBT (2.19/6.79 mGy) and higher than in FFDM (1.26/4.06 mGy) for an average breast compression thickness of 59.64 mm. A positive correlation was observed between the dose received in CESM and breast compression thickness (ρ = 0.55), and a negative correlation was observed with patient age (ρ = −0.27). No differences in dosimetric variables were observed for different compression forces.

Conclusions

The ESD and AGD in the CC projection of the right breast in CESM are higher than in FFDM but lower than in DBT. The dose had a positive correlation with breast compression thickness and a negative correlation with patient age.

对比增强光谱x线摄影（CESM）、全视场数字x线摄影（FFDM）和数字乳腺断层合成（DBT）放射剂量的比较

近年来，随着专业人员和患者对辐射剂量安全意识的提高，对比增强光谱乳房x光检查（CESM）的使用有所增加。本研究的主要目的是比较CESM、全场数字乳房x线摄影（FFDM）和数字乳房断层合成（DBT）中使用入口表面剂量（ESD）和平均腺体剂量（AGD）测量的辐射暴露。我们的第二个目的是评估乳房压缩厚度、压缩力和患者年龄造成的差异。方法回顾性观察研究纳入了2021年5月至2022年5月期间接受CESM的所有患者。从不同的CESM研究中收集ESD和AGD数据，并由两名放射科专家确定乳房密度和体积。比较分析的重点是在12个月内进行的CESM研究和FFDM或DBT中右乳房颅侧（CC）投影期间接受的辐射剂量。最后，统计分析乳房压缩厚度、压缩力和患者年龄的影响。结果77例患者参加了比较研究，44例患者参加了剂量学研究。三种乳腺成像技术在辐射剂量（ESD/AGD）上存在差异。乳房平均压迫厚度为59.64 mm时，CESM组的剂量（1.70/5.39 mGy）低于DBT组（2.19/6.79 mGy），高于FFDM组（1.26/4.06 mGy）。CESM接受的剂量与乳房压迫厚度呈正相关（ρ = 0.55），与患者年龄负相关（ρ = −0.27）。不同的压缩力在剂量学变量上没有差异。结论CESM组右乳CC投影的ESD和AGD高于FFDM组，低于DBT组。剂量与乳房压迫厚度呈正相关，与患者年龄负相关。
