Validations via ROC plot. ROC plot of the carefully selected features from 1.5-Tesla patients in diagnostic prediction on 3.0-Tesla patients. For the individual features, thresholds were estimated from 1.5-Tesla patients and then were used on the independent 3.0-Tesla patients. The resulted ROC curves were plotted in dashed lines. The ROC curves for the selected prognostic features after SVM [31–33], KNN [34] and Random Forest, [35] were plotted in solid lines.
