Fig. 3: Typical FDG PET and MIBG scintigraphy findings in individual patients with Parkinson’s disease and multiple system atrophy.
From: Differential diagnosis of parkinsonism: a head-to-head comparison of FDG PET and MIBG scintigraphy
a Spatially normalized transaxial FDG PET slices at the level of cerebellum, basal ganglia, and dorsal frontoparietal cortex. Datasets were thresholded for optimal display. b Anterior view of planar MIBG scintigraphy. The patient with PD shows a typical relative hypermetabolism of the bilateral putamen and no cardiac MIBG uptake. The MSA patient is characterized by hypometabolism of the putamen (particularly on the left side), the bilateral cerebellum, and a preserved cardiac uptake on MIBG scintigraphy. PD Parkinson’s disease, MSA multiple system atrophy.
