- Values presented as mean ± standard deviation. For the PET data, left-right averaged partial volume corrected SUVR values are shown. PD, Parkinson disease without dementia; DLB, dementia with Lewy bodies; HCS, healthy control subjects; DAT, dopamine transporter; SUVR-PV, standardized uptake value ratio partial volume corrected. Significant differences (P<0.05) between groups are indicated as follows: adifferent from HCS; bdifferent from PD and DLB; cdifferent from DLB; and ddifferent from PD.
