Figure 6 Examples of CT images (A), Heatmap (B), and their corresponding gradient-class activation maps (C) on the validation cohort. On both the heat map and the gradient class activation map, red areas indicate that the area may be associated with a high probability of survival for the patient, while blue lesions indicate a low probability of survival. (A) A 64-year-old woman with 4 years of survival after TACE and Ct-based deep learning survival prediction model activation focused on the tumor region. (B) A 52-year-old male with no internal tumor activation and a disease-free survival of 240 days. (C) The patient with the incorrect prediction, a 48-year-old male, survived 397 days after surgery. The model predicted low risk; however, death occurred after 1254 days.
