Mean SOR and Kiocc Values in Striatal Structures: Comparison of PD and Control Groups
| Parameter | Caudate | Putamen | ||||||||
|---|---|---|---|---|---|---|---|---|---|---|
| Normal | PD | %Δ | Normal | PD | %Δ | |||||
| SOR | 2.61 ± 0.17 | 2.06 ± 0.19 | −21 | 2.55 ± 0.14 | 1.68 ± 0.15 | −34 | ||||
| Kiocc | 0.0098 ± 0.0009 | 0.0066 ± 0.0014 | −32 | 0.0082 ± 0.0008 | 0.0033 ± 0.0012 | −60 | ||||

%Δ denotes change in PD group relative to control group. Values are given as mean ± SDs. SOR was calculated at 95 min after injection. R is ratio of specific striatal activity to occipital activity and is equivalent to SOR − 1. Units for Kiocc are 1/min.
