Modern Analysis of the Diagnostic Effectiveness of Digital Mammography

Abstract

Digital breast tomosynthesis (DBT)-guided biopsy is increasingly used in practice. It is important to know expected changes in biopsy targets, pathologic results, and discordance rates. In the work, the X-ray findings attributed by the radiologist to the BI-RADS categories of 4 (68 patients) and 5 (38 patients) were analyzed, depending on the nature of the histological conclusion. Digital mammography makes it possible, through computer image processing, to obtain a more accurate assessment of the pathological process in the mammary gland, which makes it possible to improve the diagnosis of early breast cancer. When analyzing the findings classified as BIRADS 4, a much higher (up to 20.59 = 4.89%) breast cancer detection rate was noted compared to analog mammography. In patients with category BIRADS 5, breast cancer was histologically confirmed in 97.37 = 6.16% of cases. The detectable node was the leading radiological symptom in the category of BIRADS 5 and was observed in 26 patients (68.42 = 6.14%). The average size of the node was 2.12 ± 0.19 cm, which corresponds to the T2 category.
