FREQUENCY OF MANIFESTATION OF UNILATERAL AND BILATERAL CHANGES IN MAMMARY GLANDS OF MATURE WOMEN ACCORDING TO SCREENING MAMMOGRAPHY DATA

Abstract

Bilateral mammography is one of the most common and informative methods of mammary gland (MG) examination, performed with the aim of primary diagnosis, quality control of treatment, etc. The aim of our study was to fi nd out the frequency of detection of unilateral or bilateral changes and calcifi cations in the mammary glands according to the results of screening mammography in a randomized sample of mature women. To achieve the goal, a randomized sample of archival anonymized mammograms of 50 women of mature age who underwent a screening or preventive examination in the mammography o ffi ce of the KP «6th City Polyclinic of Lviv»; was processed. Examinations were performed on the Fujifi lm Amulet Innova lity device (Japan) in direct (SS) and medial-l ateral oblique (MLO) projections. The results of the examinations made it possible to detect calcifi cations and assess the degree of risk of the presence of MG neoplasms using the BI-RADS scale, using the following assessment categories: 0 – incomplete examination (additional examination is required to verify the diagnosis); 1 – negative (no neoplasm detected); 2 – benign changes. In a randomized sample of mature women, the frequency of detection of calcifi cations during screening mammography was 66% (in 24% on one side, in 42% – bilaterally). Changes in the MG corresponding to the evaluation category 0 on the BI-RADS scale were found in 24% of the examined (22% – on one side, 2% – bilaterally). In 8 women (16%), structural changes were detected in combination with calcifi cations of various types. In 1 person (2%), a combination of structural changes of the MG with single calcifi cations was found bilaterally. Fragmented small- nodular fi broadenomatosis («mirror image») was visualized in the upper- lateral quadrant of the glandular triangle of both MGs.
