Value of Dual-Energy Computed Tomography Quantitative Parameters in Evaluating the Efficacy of Neoadjuvant Chemotherapy for Breast Cancer

Key Points

• The research aims to assess the effectiveness of dual-energy computed tomography (DECT) quantitative parameters in evaluating responses to neoadjuvant chemotherapy in breast cancer.
• Utilized dual-energy computed tomography to derive quantitative parameters.
• Measured changes in venous-phase ΔNIC%, ΔλHU%, and ΔED%.
• Correlated DECT parameters with treatment response in breast cancer.
• Changes in venous-phase ΔNIC%, ΔλHU%, and ΔED% were significantly associated with chemotherapy response.
• DECT-derived metrics show promise for supporting treatment response evaluation.
