Article Figures & Data
Figures
- FIGURE 1.
11C-methionine PET images in healthy subject. ROIs were enclosed manually in frontal cortex (F), parietal cortex (P), cerebellum (C), and brain stem (B).
- FIGURE 2.
w-SUVs in different parts of brain are shown as box-and-whisker plots. Box plots indicate upper and lower quartiles, median, and range. Error bars indicate farthest points that are not outliers. Significant differences were observed between frontal cortex and cerebellum, frontal cortex and brain stem, parietal cortex and cerebellum, and parietal cortex and brain stem (P < 0.01).
- FIGURE 3.
Regression analysis and scatter graph for analysis of age-associated changes in w-SUV. Although slightly negative linear regression was suggested between aging and SUV, P value of regression coefficient was not statistically significant (P = 0.485).
- FIGURE 4.
Symmetric percentage changes between first and second PET analyses in w-SUV and s-SUV are shown as box-and-whisker plots. Box plots indicate upper and lower quartiles, median, and range. Error bars indicate farthest points that are not outliers.
