Fig. 1

Comparison of the time course of dopamine transporter and dopamine D2 receptor availability between the patient with Parkinson’s disease and the patient with multiple system atrophy. Data in all striatal subregions from the first to last images were used. The horizontal and vertical axes represent the Z scores of dopamine transporter and dopamine D2 receptor availability, respectively. Black, blue, red, yellow, and green circles represent data from the ventral striatum, pre-commissural dorsal caudate, post-commissural caudate, pre-commissural dorsal putamen, and post-commissural putamen, respectively. Open and closed circles represent the patient with Parkinson’s disease and multiple system atrophy, respectively. The partial correlation, controlling for the effects of regional differences, is significant in the patient with multiple system atrophy (r = 0.893, P = 0.0002), but not in the patient with Parkinson’s disease (r = −0.036, P = 0.89)
