From: Predicting response to neo-adjuvant chemotherapy and assessment of residual disease in breast cancer using contrast-enhanced spectral mammography: a combined qualitative and quantitative approach

Type of Response Tumor largest diameter Intensity of enhancement
• Progressive disease Increase With or without change in the intensity
• Stable disease No change in size No change
• Poor response < 30% decrease Mild decrease in intensity
• Moderate response 30–60% decrease And/or moderate to marked decrease in intensity of enhancement
• Marked response > 60% decrease Residual faint enhancement
• Complete Response No residual lesion seen
