Digital tomosynthesis in breast cancer diagnostics (literature review)

Abstract

Relevance: Breast cancer is the most common malignant neoplasm among wom-en in our country. Mammography is currently the method of choice in breast can-cer diagnostics. However, it has limitations associated with the imposition of breast
 tissue layers, which makes it difficult to identify lesions and leads to a mis-diagnosis. Breast tomosynthesis is a tomographic
 technique in which the effect of tissue superimposition is significantly reduced due to layer-by-layer scanning.
 The purpose of this study was to review the capacity of tomosynthesis in the di-agnosis of breast cancer.
 Results: The combination of tomosynthesis with a synthesized image is the best technology for screening because it offers
 the best combination of efficiency and radiation dose. Advantages include greater diagnostic accuracy due to both in-creased
 sensitivity and specificity, and a significantly less need for additional mammography projections (targeted mammography,
 targeted mammography with magnification).
 Conclusions: Tomosynthesis as a diagnostic method significantly exceeds the method of mammography. The higher informative value of the results provided by tomosynthesis reduces the frequency of false-negative and false-positive radio-logical
 conclusions.
