Application of radionuclide imaging on differential diagnosis of Parkinson disease

The differential diagnosis of Parkinson disease can be challenging. Radionuclide imaging can provide the molecular and metabolic information so that it is helpful for differential diagnosis of Parkinson disease from atypical parkinsonism or other neurological disability such as essential tremor. The application of radionuclide imaging in the differential diagnosis of Parkinson disease was reviewed in this article.
