Figure 4From: Evaluation of both perfusion and atrophy in multiple system atrophy of the cerebellar type using brain SPECT alone Averaged images of spatially normalized with linear transformation and subsequent conventionally and high-dimensionally warped SPECT images in groups of MSA-C patients and normal controls. Linear spatial normalization showed insufficient transformation to a template in cerebellum (white arrows) and pons (white arrowheads) in MSA-C patients. Subsequent conventional warping could not perform a further transformation in these areas in this group. In contrast, high-dimension-warping could fully transform the cerebellum and pons to a template in MSA-C patients. Both conventionally and high-dimensionally warped SPECT images demonstrated decreased perfusion in the cerebellum and pons in MSA-C patients as compared to normal controls.Back to article page
