Abstract:
Objective The aim of this study was to investigate the characteristic of regional cerebral glucose metabolism in patients with Wilson's disease (WD) using 18F-fluorodeoxyglucose (FDG) PET.Methods Thirteen WD patients and 12 normal controls were studied by brain 18F-FDG PET, and the data were analyzed by visual analysis, semi-quantification and statistical parametric mapping (SPM). The radioactivity ratios of lenticular nuclei, caudate, thalamus and cerebellum to cerebral cortex and the ratio of lenticular nuclei to caudate were calculated, respectively. SPSS 11.0 software for statistics was also used to analyze the data. Results In WD patients, radioactivity of lenticular nuclei and candate was significantly decreased compared with controls. The radioactivity ratios of lenticular nuclei and caudate to cerebral cortex in WD patients were both significantly lower than that in normal controls (0.95±0.05 vs 1.26±0.05, t =15, P < 0.05 ; 1.02±0.06 vs 1.17±0.05, t = 8, P < 0.05), and the ratio of lenticular nuclei to caudate in WD patients was significantly higher than that in normal controls (0.93±0.06 vs 1.09±0.06, t =9, P< 0.05). Conclusion As compared with normal controls, patients with WD had significantly decreased glucose utilization in the basal ganglia, especially in the lenticullar nuclei.
