Brain regions with glucose metabolism differences between the multiple system atrophy patients with normal cognition and those with cognitive impairment.

Number	Voxels	Regions	BA	MNI coordinates			T-value
				X	Y	Z
1	186	Right superior frontal gyrus	9	12	42	48	−3.828
2	328	Right superior parietal lobule	7	34	−56	58	−3.821
3	245	Right superior frontal gyrus	6	18	−6	70	−3.619

A negative T-value signifies a decrease in glucose metabolism, and a positive T-value signifies an increase in glucose metabolism. (There is no discernible areas of increased metabolism). MNI, Montreal Neurological Institute; BA, Brodmann area.
