Fan developed a combined model including artery phase Rad-scores and serum AFP levels based on enhanced MRI to predict high Ki-67 expression (≥ 14%) in HCC, which performed better than the artery phase radiomics model in the training (AUC: 0.922 vs. 0.873) and validation cohorts (AUC: 0.863 vs. 0.813) [15]. This evidence concerns the gene MKI67 and hepatocellular carcinoma.
