[Abstract] Objective To explore the value of multiphase magnetic resonance imaging radiomics combined with different machine learning models in predicting risk stratification of hepatocellular carcinoma (HCC).Materials and Methods We retrospectively analyzed clinical and imaging data from ​​a cohort of 120 patients​​ with pathologically confirmed HCC who underwent surgery between January 2020 and December 2024, ​​all meeting predefined inclusion/exclusion criteria. Based on the Edmondson-Steiner (ES) grading system, patients were stratified into two groups: the low-grade group (ES grade Ⅰ and Ⅰ/Ⅱ; n=29) and the high-grade group (ES grade Ⅱ, Ⅱ/Ⅲ, Ⅲ, Ⅲ/Ⅳ, and Ⅳ; n=91). The cohort was subsequently randomly divided in a 7∶3 ratio into a training set (84 cases: 60 high-grade and 24 low-grade) and a validation set (36 cases: 31 high-grade and 5 low-grade). Arterial-phase MRI images were used to delineate the whole-tumor region of interest (ROI) using ITK-SNAP software. ROIs were propagated to portal venous and delayed phases via registration. A total of 3396 radiomic features were extracted using PyRadiomics. Feature selection was performed using Spearman correlation analysis, maximum relevance-minimum redundancy (mRMR), and least absolute shrinkage and selection operator (LASSO) regression. Radiomics models were constructed using five machine learning algorithms: logistic regression (LR), support vector machine (SVM), random forest (RF), naive Bayes (NB), and multilayer perceptron (MLP). The optimal radiomics model was combined with clinical imaging features to develop a combined model. Model performance was evaluated using the area under the receiver operating characteristic curve (AUC), accuracy, sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), calibration curves, and decision curve analysis (DCA).Results A total of 1132 radiomics features were extracted from three contrast-enhanced phases (arterial, portal venous, and delayed). Following dimensionality reduction and feature selection, 8 radiomics features (2 from arterial phase, 3 from portal venous phase, and 3 from delayed phase) were selected to construct radiomics models. Five machine learning algorithms LR, SVM, RF, NB, and MLP demonstrated training and validation sets AUC values of 0.899, 0.897, 0.893, 0.814, 0.876 and 0.865, 0.845, 0.590, 0.723, 0.735, respectively, for predicting HCC pathological grades, indicating that the LR model exhibited the best performance and stability. Univariate and multivariate logistic regression analyses of clinical-radiological features identified age (P = 0.046) and alpha-fetoprotein (AFP) (P = 0.031) as independent predictors of HCC pathological grading. These predictors were subsequently integrated with the radiomics model to develop a combined model, achieving AUC of 0.929 (training set) and 0.884 (validation set). DeLong test revealed significant differences between the clinical model versus the radiomics model and combined model in the training set (P < 0.05), while no statistical distinction was observed between the radiomics and combined models (P > 0.05). In the validation set, no significant differences were found among the three models (P > 0.05). Calibration curves demonstrated closer alignment between predicted and actual probabilities for the combined model in both sets. DCA indicated enhanced net clinical benefit within clinically relevant threshold probabilities. Ultimately, the combined model integrating clinical and radiomics features provided a more accurate prediction of HCC pathological grading.Conclusions The integration of multiphase dynamic contrast-enhanced MRI radiomics with clinical imaging features enables accurate prediction of HCC risk stratification.
