We proposed a machine learning method to distinguish Parkinson’s disease from normal controls based on five brain nuclei visualized in STAGE imaging. The final radiomics model achieved an AUC of 0.948 in the testing dataset.
Figure 2. Flowchart for the radiomics experiments. The last inset on the right contains the tuning feature number in the model with 5-fold cross-validation. A total of 28 features were kept in the final model when the 1-SE rule was used (top). The ROC curves for the final model over training and testing datasets (bottom).
