Role of Contrast-Enhanced Spectral Mammography in the detection of breast cancer

Objective : to assess the benefits of using contrast-enhancer spectral mammography in patients with an established category of BI-RADS 4a, 4b according to the results of a standard examination (digital mammography and ultrasound). Materials and methods . The date of 425 patients with a suspicious category of BI-RADS in the period from 2018 to 2021 were analyzed. As part of the additional examination, all patients underwent contrast-enhanced spectral mammography follow by histological verification of the identified changes. The sensitivity and specificity of the methods were evaluated. Results . The final diagnosis of breast cancer was established in 247 (58.1%) patients out of 425 women. Multicenter and multifocal growth was diagnosed in 17 (6.8%) patients out of 247, and primary multiple synchronous cancer was detected in 6 (2.4%) patients out of 247. False-positive cases when assessing CESM mainly consisted of: typical and atypical ductal hyperplasia, fibroadenoma, intraductal papilloma. Conclusion . Contrast-enhancer spectral mammography is a highly sensitive and highly specific method in the detection of malignant tumors of the breast. The method also allows minimizing the number of unwanted interventions in suspicious BI-RADS categories.
