Development and validation of combined Ki67 status prediction model for intrahepatic cholangiocarcinoma based on MRI radiomics

In the past decades, the incidence and mortality of intrahepatic cholangiocarcinoma (ICC) have been on the rise. A nuclear antigen named Ki67 is a poor prognostic predictor and an attractive therapeutic target in patients with ICC. Therefore, accurate prediction of Ki67 status in ICC patients is a predictor for treatment efficacy evaluation and outcome prediction. In this study, we established a multiparametric model for predicting Ki67 status in ICC patients preoperatively.
