ДИФФЕРЕНЦИАЛЬНАЯ ДИАГНОСТИКА ПАТОЛОГИИ МОЛОЧНОЙ ЖЕЛЕЗЫ С ПОМОЩЬЮ ТИПОВ НАКОПЛЕНИЯ КОНТРАСТНОГО ПРЕПАРАТА ПРИ КОНТРАСТНОЙ СПЕКТРАЛЬНОЙ ДВУХЭНЕРГЕТИЧЕСКОЙ МАММОГРАФИИ

Dual-energy contrast-enhanced spectral mammography (CESM) is a new promising method for visualizing pathological changes in breast, which combines digital mammography and a functional assessment of vascularization using intravenous contrast ehnancement. According to accumulated experience CESM is well tolerated by patients and is similar to magnetic resonance imaging with dynamic contrast enhancement (MRI with DCE), but at the same time, CESM is more affordable and can be performed in patients with contraindications for MRI. However, few studies have been conducted to evaluate the role of CESM. In the world literature, interpretation of contrast images is based only on the degree of accumulation of the contrast agent, but we propose a more detailed assessment of the structure of the hypervascular lesions by highlighting the contrast enhancement patterns. Objective: to determine the diagnostic effectiveness of CESM using the contrast enhancement patterns in malignant and benign lesions...
