Prediction of lymphovascular invasion in rectal cancer based on multimodal magnetic resonance imaging radiomics model

Figure 5 Receiver operating characteristic curve comparison of different models (test set). Receiver operating characteristic curves comparing the diagnostic performance of the combined model [area under the curve (AUC) = 0.867], multimodal radiomics (AUC = 0.835), clinical model (AUC = 0.782) and T1-weighted contrast-enhanced imaging alone (AUC = 0.775) for predicting neural invasion. The dashed diagonal indicates the reference line (AUC = 0.5). AUC: Area under the curve; T1CE: T1-weighted contrast-enhanced imaging.
