Figure 2

Signal intensities of the substantia nigra (SN) and the globus pallidus internus (GPI) in the different groups given in arbitrary units (a.u.). Plot shows 10th, 25th, 50th, 75th, and 90th percentiles and outliers. A: Signal intensities of the right SN. B: Signal intensities of the left SN. C: Signal intensities of the right GPI. D: Signal intensities of the left GPI. The comparison between PD and CON was significant for SN on both sides at p < 0.001. For the GPI on both sides, the statistical comparison between PD and CON as well as between PSP and CON showed differences at p < 0.001. Abbreviations: PD = Parkinson’s disease, MSA = multisystem atrophy, PSP = progressive supranuclear palsy, CBS = corticobasal syndrome, CON = control persons.
