Figure 1.

A 34-year-old male with a clearly bounded solitary HCC and M0 status, (A-D) exhibits persistent enhancement in AP, PVP, DP, and a smooth tumor margin (red arrow). A 52-year-old male with HCC and M1 grade, which illustrates a typical no/mini enhancement (red arrow) (E-G). Vague margin is visible at the superior edge of the tumor (black arrowhead) (H). A 65-year-old male who had HCC with M2 status was detected. The mass has a Max/Min-R of 1.59 and heterogeneous moderate hyperintensity on T2WI (I), which displays no or minimal enhancement (red arrow) on AP, PVP, and DP(J-L). The lesion appears as extranodular nodule (black arrowhead) (L).

(A,B) The MVI nomogram was built by incorporating four variables, and among the MVI-positive cases, three variables were used to establish another nomogram for predicting M2 grade. (C,D) Calibration curves of the nomogram in predicting MVI and its M2 grade. X-axis, nomogram-predicted probability of MVI or M2; Y-axis, observed MVI or M2. (E,F) Nomogram model (blue line) outperforms all (red line) and none (horizontal green line) across all reasonable threshold probabilities in predicting MVI and its M2 grade. (G,H) The ROC curves demonstrate the discriminatory ability of the two nomograms of MVI positive and its M2 grade.
