Bilateral increases in FMT uptake correlate with reductions in clinical rating scale (CRS) scores. Shown are independent correlations between the percentage change in CRS score 6 months after treatment and the percentage increase in FMT-PET signal for the left and right putamen of AAV2-GDNF (A and B) and control (C and D) monkeys. AAV2-GDNF monkeys displayed a significant linear correlation (solid lines) between changes in CRS score and PET signal for both the partially lesioned left putamen (A) and fully lesioned right putamen (B). Correlations for the control monkeys (dotted lines) were not statistically significant for either the partial (C) or the fully (D) lesioned hemisphere.
