Evaluating microvascular invasion in hepatitis B virus-related hepatocellular carcinoma based on contrast-enhanced computed tomography radiomics and clinicoradiological factors

Figure 4 Calibration, discrimination, and clinical utility analysis of the radiologic-radiomics model for predicting microvascular invasion. A: Receiver operating characteristic analysis curve of the model; B-D: Calibration curves in the training (B) and validation (C) datasets, and decision curve (D) in the overall patients; E: The model is presented with a nomogram scaled by the proportional regression coefficient of each predictor. AFP: Alpha-fetoprotein; MVI: Microvascular invasion; radscore (ROI^tumor-DP): Represents the radscore based on regions of interest of tumor from delayed phase contrast-enhanced computed tomography images; ROC: Receiver operating characteristic; AUC: Area under the curve.
