85-0.88 for arterial invasion and 0.92-0.87 for venous invasion. Using criteria of circumferential interface ≤ 180° with contour deformity ≤ grade 2 and/or length of tumor contact less then 2 cm to predict R0 resection, the AUCs was 0.85-0.86 for the two readers. The overall inter-reader agreement was good (κ = 0.75-0.8. The κ values for venous invasion, arterial invasion and R0 resection were 0.76, 0.78, and 0.80. Conclusion Tumor-vessel criteria demonstrated good diagnostic performance and reproducibility in the prediction of vascul
