Brain perfusion differences between Parkinson's disease and multiple system atrophy with predominant parkinsonian features.
2005
Abstract Background The patterns of regional cerebral blood flow in Parkinson's disease and multiple system atrophy remain inconsistent. Objectives To compare brain perfusion images of 123 I-IMP SPECT between Parkinson's disease, multiple system atrophy with predominant parkinsonian features (MSA-P) and controls. Methods Eighty-two patients with Parkinson's disease, 10 patients with MSA-P and 14 controls were studied. We performed 3D-SSP and volume of interest analysis using 123 I-IMP scintigraphy. Results Occipital perfusion of MSA-P increased compared to that of Parkinson's disease and perfusion in the cerebellum and primary sensorimotor cortex of Parkinson's disease increased compared to that of MSA-P. Perfusion in the putamen of MSA-P decreased compared to that of Parkinson's disease. Conclusion Our study demonstrated perfusion differences in 123 I-IMP SPECT between the two diseases.
