Study of dynamic CT radiomic features to assist the accurate diagnosis of HCC

Figure 1 Delineation of an HCC in each of the five phases on CT images (A: plain scan phase (PSP), B: arterial phase (AP), C: portal venous phase (PVP), D: venous phase (VP), E: delayed phase (DP)) Figure 2 The variation trend of the GTV radiomic features throughout the 5 phases Figure 3 The comparison of dynamic trends of the CT radiomic features of the GTV and normal liver tissue Figure 4 ROC curves of 4 radiomic features in the five phases (A: plain scan phase, B: arterial phase, C: portal venous phase, D: venous phase, E: delayed phase） Table 1 The radiomic feature change rate differences between normal liver tissue and the GTV in the different time phases Table 2 The AUC values and Youden index of 4 radiomic features in the different phases Table S1 The extracted radiomic features in this study
