Magnetic resonance imaging-based radiomics signature for predicting preoperative staging of esophageal cancer

Figure 2 Receiver operating characteristic curves of the radiomics signature’s discriminative performance in esophageal cancer staging in the primary and validation cohorts. A: Primary cohorts; B: Validation cohorts. The combined radiomics signature demonstrated superior area under the curve (AUC) in both the primary (AUC: 0.877) and validation cohorts (AUC: 0.851), outperforming single-sequence models. AUC: Area under the curve; T1WI: T1-weighted imaging; T2WI: T2-weighted imaging.
