TABLE 2.

Striatal Cholinergic Binding Increase in PD Group Compared with Control Group

Striatal region	P	Cluster size	Montreal Neurologic Institute coordinates (x, y, z) of maximum peak	Peak-level t value
MA putamen	0.028	369 voxels	−32, −8, 5	3.93
Least affected putamen	0.043	188 voxels	32, −9, 6	4.15

P value is corrected for multiple comparisons at cluster level by using familywise error approach.
