Description of intervention(s) / exposure
We propose to perform F-DOPA Positron Emission Tomography (PET) scans in 20 participants with typical clinical features of Parkinson’s disease (PD). Images will be compared to their standard care Magnetic Resonance Imaging (MRI) scans to identify brain structures. Previous MRI scans, performed within the last 12 months, will be selected for comparison to PET scans. All participants will be monitored for the duration of the PET scan appointment (approximately 4 hours). No additional follow-up will be performed on this study.

Not applicable
Comparator / control treatment
We propose to perform one F-DOPA Positron Emission Tomography (PET) scan and one Magnetic Resonance Imaging (MRI) scan on 10 healthy volunteer controls. MRI scans will be used to identify brain structures. The F-DOPA PET scan will be performed within 4 months of the MRI scan. Participants will be observed for 4 hours while attending the PET scan appointment and 1 hour during the MRI scan appointment. No additional follow-up will be performed on this study.

Outcomes
Primary outcome [1] 304703 0
Difference in the striatoccipital ratio (SOR) between health controls and Parkinson's disease (PD) subjects by assessment of FDOPA brain activity on PET scans.
Timepoint [1] 304703 0
At completion of all subject imaging at the end of the study.
Secondary outcome [1] 342857 0
Estimate the diagnostic yield (sensitivity and specificity) of F-DOPA PET-CT scans in differentiating between normal healthy subjects and subjects with early and advanced-stage Parkinson's disease by assessing brain structures on MRI and brain activity on the FDOPA PET scan.
Timepoint [1] 342857 0
At completion of all subject imaging at the end of the study.
Secondary outcome [2] 343448 0
We will record any adverse events that occur in any group during the PET imaging process to assist in the assessment of the safety of F-DOPA PET imaging, although no adverse events from this procedure are anticipated..
Timepoint [2] 343448 0
At completion of all participant imaging.

Statistical methods / analysis
Based on previously published data from Groningen University Hospital, the mean contralateral striato-occipital ratio (SOR) was 2.69 (SD 0.27) in healthy controls compared with a mean of 2.09 (SD 0.14) in earlystage Parkinson's disease (PD). Assuming a difference of a similar magnitude in our participant population, we estimate a minimum sample size of 4 subjects to demonstrate a statistically significant difference in contralateral SOR between healthy controls and early-stage PD subjects with a power of 0.99 and type I error rate of 5% (2 sample, 1-sided t-test).
