Our study suggests that the metabolic pattern analysis of 18F-FDG PET has high diagnostic accuracy in the differential diagnosis of parkinsonian disorders.
We report the F-FDG and F-florbetapir dynamic PET images (early and delay phases) of an 83-year-old woman with cognitive impairment associated with visual hallucinations and parkinsonism due to probable DLB.
Taken together, the current literature underscores the utility of <sup>18</sup>F-FDG PET for diagnostic evaluation of parkinsonism and the promising role of <sup>18</sup>F-FDG PET for assessment and risk stratification of cognitive impairment in PD.
