The improvement of methods of radiation diagnostics has led to an increase in the frequency of detection of breast cancer in the early stages. According to our study (a retrospective analysis of data from 195 MRM with DKU), the results of studies of women with a histologically verified diagnosis of intra-ductal carcinoma in situ (DCIS). For formations of more than 5 mm in 60 %, we obtained reliable criteria for the malignant process (contrast capture of more than 100 % for type II-III, the presence of feeding arteries). Various contrast zones without / or with the presence of less than 5 mm formation in 10–20 % of in situ carcinomas had a pattern of accumulation similar to benign proliferative changes, a statistically significant criterion was the strengthening of the vasculature on MIP reconstruction around the contrast zone, which in 31 % of cases coincided with the areas of accumulation of atypical microcalcinates detected in mammography (BI-RADS 4). MR mammography with dynamic contrast enhancement, having a high sensitivity in detecting vascularized areas, allows us to assess their nature with a high degree of probability against the background of any types of breast tissue structure.
