Receiver-operator characteristic curve derived from DTI-FA maps of 20 PD & 22 healthy controls left-out of analysis pool. Receiver operator characteristic curve derived from DTI-FA maps of 20 PD & 22 healthy controls for detection of subjects left out of analysis. Cluster-thresholding at various voxel-wise thresholds (dotted) provide marginal prediction in our hands. The PI’s RMRD method had improved accuracy (dashed lines). A bootstrapping approach (heavy solid red line) was the most predictive
