Fig 2. Differences in DaT-SPECT uptake between groups within VOIs.

Mean standardized DaT-SPECT values obtained in the striatum VOIs in the three groups. NMNC = non-manifesting non-carriers of LRRK2 mutations, NMC = non-manifesting LRRK2 mutations carriers; (*significant group differences, p<0.05, corrected for age and for multiple comparisons).
