Early prognostic stratification is desirable in patients with suspected atypical parkinsonian
syndromes (APSs) for optimal treatment and counseling. We investigated the prognostic …

Purpose It is often difficult to differentiate parkinsonism, especially when patients show
uncertain parkinsonian features. We investigated the usefulness of dopamine transporter …

Background Atypical parkinsonism (AP) often presents with Parkinson's symptoms but has a
much worse long-term prognosis. The diagnosis is presently based on clinical criteria, but a …

Purpose Regional cerebral perfusion is coupled to metabolism in general. Early perfusion
dominant imaging using 18 F-FP-CIT PET (pCIT) may provide complementary information to …

Accurate differential diagnosis of parkinsonism is of paramount therapeutic and prognostic
importance. In addition, with the development of invasive therapies and novel disease …

Background and purpose Atypical Parkinsonian disorders (APD) frequently overlap in
clinical presentations, making the differential diagnosis challenging in the early stages. The …

Aim The aims in this study were to evaluate the role of brain 18 F-FDG PET imaging in
differential diagnosis of parkinsonism and to correlate brain metabolism findings with …

Purpose Dopamine transporter (DAT) imaging can demonstrate presynaptic dopaminergic
neuronal loss in Parkinson's disease (PD). However, differentiating atypical parkinsonism …

Objective: Imaging of regional cerebral glucose metabolism with PET and striatal dopamine
D2/D3 receptors (D2R) with SPECT improves the differential diagnosis of parkinsonism. We …

Purpose There are no comprehensive guidelines for the use of FDG PET in the following
three clinical scenarios:(1) diagnostic work-up of patients with idiopathic Parkinson's …
