Visualization of the DLM using the Grad-CAM. CDFI and activation maps of 6 types of lumps are shown. The strong response areas (red areas) are also the areas the DLM paid more attention to, which also means that these areas are more valuable for response prediction. The ovals represent the common areas of concern of the radiologist and the DLM; the squares represent the areas of greater concern of the radiologist; the triangles represent the areas of greater concern of the DLM. CDFI, color Doppler flow imaging; DLM, deep learning model
