TL;DR: Results showed that the joint Burg entropy prior far outperformed the conventional anatomical priors in terms of preserving PET unique lesions, while still reconstructing functional boundaries with corresponding MR boundaries, and are therefore likely to increase the diagnostic confidence in MR-guided PET image reconstructions.

TL;DR: The findings from this study showed serotonergic hyperinnervation in the grafted striatum of two patients with Parkinson's disease who exhibited major motor recovery after transplantation with fetal mesencephalic tissue but later developed graft-induced dyskinesias, which were significantly attenuated by administration of a serotonin agonist.

TL;DR: To determine whether iron deposition in deep brain nuclei assessed using high‐pass filtered phase imaging plays a role in motor disease severity in Parkinson's disease, data are analyzed through positron emission tomography and electrophysiology.

TL;DR: Measuring microstructure alterations with diffusion tensor imaging in PD is potentially a valuable tool to use as a biomarker for early diagnosis and to track disease progression.

TL;DR: An overview of neuroimaging applications in patients with DLB is provided and novel PET molecular imaging modalities, such as amyloid and tau imaging, may provide further insights into DLB pathophysiology and may aid in early diagnosis.
