Gadoxetic Acid-Enhanced MRI-Based Radiomics Signature: A Potential Imaging Biomarker for Identifying Cytokeratin 19-Positive Hepatocellular Carcinoma

Figure 5

Calibration plot of the fusion radiomics signature in prediction of CK19 status. The probabilities predicted by the fusion radiomics signature (“apparent,” red line) and the bootstrap model (2000 times) (“bias-corrected,” blue line) showed a good consistency. The dashed diagonal represents an “ideal” situation in which the model predicted probability perfectly equals to the observed probability.
