Research progress of radiomics inpredicting microvascular invasion of intrahepatic cholangicarcinoma
Intrahepatic cholangiocarcinoma(ICC)is the second common malignant tumor originating in the liver,and its incidence is rising worldwide.Microvascular invasion(MVI)is a considerable poor-prognostic factor in ICC.Radiomics transforms image information into intuitive data to reflect tumor internal heterogeneity by extracting quantitative features from medical images with high throughput,which important value in predicting ICC MVI before surgery has been proven.However,the optimal radiological method,radiomics features,independent predictors,and other key issues related to the prediction model of ICC MVI remain unclear,and research on peritumoral radiomics is also lacking.This review will stress these issues by providing a comprehensive review on ICC MVI prediction before surgery from the four sections of computed tomography(CT),MRI,positron emission tomography(PET)and ultrasound(US).The aim of this paper is to promote the accurate diagnosis and treatment of ICC MVI for clinicians.
