Box-and-whisker plots of the SBR-Q (a), PCR-Q (b), AI-Q (c), SBR-V (d), FD-V (e), and AI-V (f). There were significant differences in all six quantitative indices between NPS and PS, as assessed using the Mann-Whitney U test. Abbreviations: AI, asymmetry index; FD, fractal dimension; NPS, non-parkinsonian syndrome; PCR, putamen-to-caudate ratio; PS, parkinsonian syndrome; SBR, specific binding ratio
