PD-related spatial covariance pattern. (A) Parkinson's disease (PD)-related pattern (PDRP) identified by network analysis of 18F-FDG PET scans from PD patients and age-matched normal controls. This spatial covariance pattern was characterized by metabolic increases in the pallidum, thalamus, pons, and cerebellum, associated with decreases in the premotor and posteriorparietal-occipital areas. Cerebral regions with metabolic increases are color coded from red to yellow, while those with metabolic decreases are color coded from blue to purple. (B) PDRP expression (subject scores) was increased in patients with PD relative to the normal subjects. P value was assessed by independent two sample t-test and differences in PDRP scores between two groups reached significance (P < 0.001). (C) Correlations between PDRP expression and clinical indicators of disease severity in PD. Subject scores in individual patients presented significant correlation with the Unified Parkinson's Disease Rating Scale motor ratings (UPDRS).

MSA-related spatial covariance pattern. Multiple system atrophy (MSA)-related pattern (MSARP) identified by network analysis of 18F-FDG PET scans from MSA patients and age-matched normal controls. This pattern was characterized by metabolic decreases in the putamen and the cerebellum. Cerebral regions with metabolic metabolic decreases are color coded from blue to purple.

PSP-related spatial covariance pattern. Progressive supranuclear palsy (PSP)-related pattern (PSPRP) identified by network analysis of 18F-FDG PET scans from PSP patients and age-matched normal controls. This pattern was characterized by metabolic decreases in the medial prefrontal cortex, ventro lateral prefrontal cortex (VLPFC), caudate nuclei, medial thalamus and the upper brainstem putamen. Cerebral regions with metabolic metabolic decreases are color coded from blue to purple

Comparison of abnormal cerebral metabolic regions in patients with mild and severe Parkinson's disease (PD). In patients with early PD, cerebral hypermetabolism was detected in the thalamus, lentiform nucleus and cerebellum, while hypometaboIism was not observed in any subregions. In those with advanced PD, the hypermetabolism was also found in the thalamus, lentiformnucleus and cerebellum, with a higher magnitude in glucose metabolism rate. Meanwhile, hypometabolism was observed in bilateral parietal lobules. Cerebral regions with metabolic increases are color coded from red to yellow, while those with metabolic decreases are color coded from blue to purple.
