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
