Biparametric magnetic resonance imaging-based radiomic and deep learning models for predicting Ki-67 risk stratification in hepatocellular carcinoma

Figure 5 Recurrence-free survival curves obtained from Kaplan-Meier analysis were scaled for high Ki-67 risk stratification. A: High Ki-67 expression was confirmed by histopathology; B: High Ki-67 expression was predicted by the nomogram model; C: Ki-67 risk stratification was further diagnosed by histopathology; D: Ki-67 risk stratification was further predicted by the nomogram model.
