Results: The early MSAC group showed highly significant atrophy in the whole cerebellum and basal ganglia (putamen and pallidum) (p < 0.001), and significant atrophy in some regions of frontal, occipital and parietal lobes (p < 0.05).The late MSA-C group showed more atrophied regions in the same atrophied lobes of early MSA-C, and revealed more atrophied regions in limbic, occipital and temporal lobes.
