The parametric comperison of digital synthetic mammography with tomosynthesis and standard mammography

Sa？etak Aim: The main goal of our research is to compare the thickness of the breast and the parameters of DBT and standard 2D mammography. Respondents and methods: The study included 200 respondents with an age range from 40 to 81 years, (median 60,5 ± 10,6). The respondents are divided into 2 groups depending on the type of mammograms they were subjected to. This retrospective analysis included tests performed on the mammography device Hologic Selenia Dimensions (Hologic, Bedford, Mass) in the period from February, 1st till March, 30th 2018. Results: Hi-square test excluded statistically significant difference in breast density. The T-test didn’t show any statistically significant difference in breast thickness between two groups. The mean values of the overall glandular dose of the DBT for left and rigt breast were 0.53 mGy and 0,37 mGy, respectively (3.83 / -1mGy, p = 0.001, 3.82 / -0.9 mGy, p = 0.023). The difference was statistically significant and dose was 20% greater in DBT. Conclusion: Despite the statistically significant difference in the absorbed glandular dose between the two groups, it remains within the limits of acceptability according to the guidelines provided by the Ordinance on Conditions for application of sources of ionizing radiation for the purpose of medical and non – medical irradiation (OG 42/2018, 9.5.2018). Digital breast tomosynthesis with S-mammography is an important imaging modality in early detection of pathological breast changes
