摘要

目的:探讨女性乳房大小、乳腺密度与全场数字乳房x线摄影(FFDM)乳房辐射剂量的关系,以及影响辐射剂量的因素。材料和方法:该研究包括来自515名连续参与者的2,060张FFDM图像。参与者被分为高剂量组(>3 mGy)和低剂量组(结果:乳房x线摄影平均体积为936.2±425.2 (114.5-3,018)mL,平均压缩乳房组织厚度为56.75±10.44 mm)。高剂量组平均MGD为3.51±0.48 mGy,低剂量组平均MGD为1.92±0.56 mGy。高剂量组乳房的厚度、直径、体积、压迫压力和手术率均较大。然而,高剂量组更年轻,乳房密度更低。在多因素logistic回归分析中,最重要的剂量决定预测因子是乳房厚度[比值比(OR): 1.178, 95%可信区间(CI): 1.156-1.200],结论:乳房体积越大的女性接受的辐射剂量越高。因此,乳房筛查项目可以针对乳房体积较大的年轻女性和做过保乳手术的女性进行个体化治疗。

The Effect of Breast Size and Density in Turkish Women on Radiation Dose in Full-Field Digital Mammography.

The Effect of Breast Size and Density in Turkish Women on Radiation Dose in Full-Field Digital Mammography.

The Effect of Breast Size and Density in Turkish Women on Radiation Dose in Full-Field Digital Mammography.

Objective: The purpose of this study was to look into the relationship between breast size and mammographic breast density in women and breast radiation dose on full-field digital mammography (FFDM), as well as the factors that influence radiation dose.

Materials and methods: The study included a total of 2,060 FFDM images from 515 consecutive participants. The participants were divided into two groups: those exposed to high doses (>3 mGy) and those exposed to low doses (<3 mGy). Moreover, the researchers analyzed the relationship between mean glandular dose (MGD) of the breast and patient age, compressed breast thickness, compression force, mammographic breast composition, and mammographic breast size.

Results: The mean mammographic breast volume was 936.2 ± 425.2 (114.5-3,018) mL, and the mean compressed breast tissue thickness was 56.75 ± 10.44 mm. Moreover, the mean MGD in the high-dose group was 3.51 ± 0.48 mGy and 1.92 ± 0.56 mGy in the low-dose group. The high-dose group had greater breast thickness, diameters, volume, compression pressure, and surgical rate. However, the high-dose group was younger and had less dense breasts. In multivariate logistic regression analysis, the most important predictors of dose determination were breast thickness [odds ratio (OR): 1.178, 95% confidence interval (CI): 1.156-1.200, p<0.001], history of previous surgery (OR: 2.210, 95% CI: 1.417-3.447, p<0.001), compression force (OR: 1.008, 95% CI: 1.004-1.013, p<0.001), and breast density (OR: 1.873, 95% CI: 1.359-2.580, p<0.001).

Conclusion: Women with larger breast volumes are subjected to higher doses of radiation. Therefore, breast-screening programs can be individualized to young women with larger breast volumes and women who have had breast-conserving surgery.
