Summary

The role of PET for the in vivo study of the presynaptic dopaminergic system with 11C-Fe-CIT is universally recognized, and its use has also become routine in numerous nuclear medicine centers in Europe. The indication for the examination is provided exclusively by the clinic in the presence of extrapyramidal signs in the suspicion of Parkinson's disease (PD) or for the differential diagnosis of parkinsonisms. The existence of factors that influence the prognosis of patients with PD or parkinsonism associated with other degenerative diseases is known.

Given these premises, the possibility of identifying the disease in the early stages appears fundamental.

For this purpose the following should be considered:

1. an automatic analysis method based on the measurement of radiotracer uptake at the level of individual voxels, following Statistical Parametric Mapping procedures.
2. the analysis based on regions of interest (ROIs) positioned ad hoc by the operator which will give the value of the ROI to reference region ratio. In particular, ROIs on the basal ganglia (caudate, putamen) towards cerebellum.

Both of these methods offer a quantitative measurement of the damage at the level of the structures involved that is absolutely better than the visual investigation of the distribution of radioactivity in the central nervous system.

In this study the investigators want to compare results provided by methods 1 and 2 in the populations under examination to evaluate the data relating to the specificity and sensitivity of the test.
