Radiomic features were extracted from regions of interest on arterial and venous phase CT scans. LASSO logistic regression was used to select 36 features for building ML models, including random forest, logistic regression, support vector machine, and artificial neural networks. An integrated nomogram combining radiomic features and CA19\u20109 levels was developed to distinguish PDAC from borderline tumors. Model performance was evaluated using receiver operating characteristic (ROC) curves, calibration curves, and decision curve analysis.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>All ML models effectively differentiated the three tumor types. The random forest algorithm showed the best performance, achieving an area under the curve (AUC) of 0.99 and 0.95 in the training and validation sets, respectively. CA19\u20109 was identified as an independent diagnostic factor for PDAC. The nomogram integrating radiomics and CA19\u20109 achieved an AUC of 0.89 and accuracy of 0.85 in the training set, with corresponding values of 0.85 and 0.82 in the validation set.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Radiomics\u2010based ML models effectively differentiated benign, borderline, and malignant pancreatic tumors.
