A) Scatter plot and receiver-operating-characteristic (ROC) curve for the Parkinson's disease (PD)-related metabolic brain pattern by using 17 healthy controls (HC) and 19 PD (PD) patients (PDRP-mCT17HC19PD). On the y-axis of the scatter plot the leave-one-out z-scores are displayed and on the x-axis the healthy control group and the PD patient group. * = Inflection point on the ROC curve (z-score); y-axis ROC curve = sensitivity, x-axis ROC curve = 1 − specificity; PPV = positive predictive value; NPV = negative predictive value.B) Scatter plot displaying z-scores for healthy controls and Parkinson's disease patients scanned on the high resolution mCT camera (17HC-mCT and 19PD-mCT (first two columns)) by using the previously published metabolic brain pattern on the HR+ camera (Teune et al., 2013) (PDRP-HR18HC20PD) as a reference. In the third and fourth columns z-scores are displayed for the HC and PD subjects scanned on the HR+ camera (18HC-HR and 20PD-HR) by using PDRP-mCT17HC19PD as a reference.C) Scatter plot displaying z-scores for healthy controls and Parkinson's disease patients and their FDG and PCASL scans (17HC-FDG, 17HC-PCASL, 14PD-FDG and 14PD-PCASL respectively) by using the PD-related metabolic brain pattern (PDRP-mCT17HC19PD) as a reference.
