Visual analyses of 18F-DOPA PET/MRI according to the international guidelines [11]. A This IPD patient, visually considered normal. The clinical follow-up and had symptoms relief after L-DOPA therapeutic test classified him as FN. Only min SUVr was below the 95% confidence interval estimated from controls. B This IPD presented unilateral right posterior putamen (white arrow) pre-synaptic dopamine denervation and global striatal 18F-DOPA decrease with faintly increased background unspecific activity. PET right putamen dopamine denervation was confirmed with symptoms relief after L-DOPA therapeutic test
