Developing and validating a computed tomography radiomics strategy to predict lymph node metastasis in pancreatic cancer

Figure 3 Diagnostic performance of the Radscore model. A and B: Distribution of Radscore values for predicting LNM in the training (A) and test (B) cohorts. Blue dots represent patients without LNM, and yellow dots represent those with LNM; C and D: Receiver operating characteristic curves of the Radscore model for the training (C) and test (D) cohorts. Radscore_A refers to the model derived from arterial phase computed tomography images, while Radscore_P refers to the model derived from portal venous phase images. The area under the curve was used to evaluate model performance.
