Fig. 2: Direct comparison of FDG and FDOPA uptake between follow-up and baseline.
From: Longitudinal trimodal imaging of midbrain-associated network degeneration in Parkinson’s disease

Patients showed significantly reduced FDG uptake in the left midbrain (a) and significantly reduced FDOPA uptake in the right caudate (c) at follow-up visits compared to baseline. Both clusters are displayed in binarized form. Results were obtained by applying the above stated contrasts, thresholded at pFWE < 0.05 cluster-level corrected with SVC for midbrain (a) or striatum (c), respectively. Progression plots show the decrement of tracer uptakes between both visits for each patient individually for left midbrain FDG uptake (b) and right caudate FDOPA uptake (d). Progression plots contain extracted normalized FDG and FDOPA values with proportional scaling. BL = baseline, FU = follow up, HC = healthy controls.
