Voxel-wise analysis of treatment responders compared to non-responders. Increased dopamine synthesis capacity, relative to non-responder patients (N = 13), in patients who respond to treatment (N = 13). The most significant increase was in voxels in right caudate (Peak MNI coordinates x = 18, y = 20, z = 2; p_{FWE corr} = 0.026) and left putamen (Peak MNI coordinates x = −24, y = 8, z = −2; p_{FWE corr} = 0.027)
