Preoperative Prediction of Axillary Lymph Node Metastasis in Breast Cancer Based on Intratumoral and Peritumoral DCE-MRI Radiomics Nomogram

Figure 3

(a) A radiomics nomogram was developed in the training cohort, incorporating the radiomics signature, MR-reported maximum diameter of the lesion, and MR-reported axillary lymph node (ALN) status. Comparison of receiver operating characteristic curves between the radiomics nomogram, intratumoral model, peritumoral model, intratumoral model, intratumoral combined with peritumoral model and model, and MR-reported ALN status alone for the prediction of ALN metastasis in the training (b) and validation (c) cohorts. Calibration curves of the radiomics nomogram in the training (d) and (e) validation cohorts.
