  18F-AV133 PET-CT scan of the patient shows significant decrease in uptake in the bilateral putamen. (B)
  18F-AV133 PET-CT scan of a healthy person shows symmetrical uptake in both the bilateral caudate nucleus and the putamen. White enclosed lines distinguish between the anterior putamen and the posterior putamen. Red arrow: caudate nucleus; white arrow: anterior putamen; yellow arrow: posterior putamen.

case_images: The mean standardized uptake value ratios (SUVRs) for the left posterior putamen, right posterior putamen, left anterior putamen, and right anterior putamen were 2.14, 2.18, 2.15, and 2.45, respectively [the mean SUVRs for a healthy person are 5.12, 6.05, 5.36, and 5.36, respectively, and the reference diagnostic value distinguishing PD patients from healthy controls in the posterior dorsal putamen is 3.43 ], revealing a significant decrease in uptake in the bilateral putamen (Figure 1).
