- PD is a common neurodegenerative disorder, and it is important to distinguish between PD and other PS including essential tremor, drug-induced, vascular, and psychogenic parkinsonism.
- Clinical differentiation between PD and other causes of Parkinsonian syndromes is not always possible and accurate diagnosis is necessary for treatment selection.
- Brain 18F-DOPA PET scan is a useful tool to study the dopaminergic pathway to differentiate PD from other PS. It’s also indicated to detect early onset PD with mild symptoms, atypical cases and to evaluate patients with no appropriate response to treatment.
- In PD patients 18F-DOPA PET shows a characteristic pattern of striatal decrease uptake from the back to the front, first losing the “tail” of the “comma”. This pattern is not present in other PS.
