Decreased cholinergic activity in specific brain regions associated with slower lower limb visual choice reaction time in Parkinson’s disease: A [18F]-FEOBV PET study
Objective: To investigate the relationship between cholinergic system changes, as measured by vesicular acetylcholine transporters (VAChT) [18F] fluoroethoxybenzovesamicol ([18F] FEOBV) binding in PET, and cognitive performance, measured as…Brain Energetics: Changes in Healthy Aging and Parkinson’s Disease
Objective: To identify in vivo bioenergetic alterations in healthy aging and Parkinson’s disease (PD). Background: PD-related cerebral metabolic alterations have been robustly characterized [1] and…Striatal Dysfunction in Parkinson’s Disease Progression: A 18F-9-fluoropropyl-(+)-dihydrotetrabenazine(18F-AV133) PET Study
Objective: To investigate the patterns of striatal 18F-AV133 uptake in relation to disease progression across different stages of PD and to examine its relationship with…Comparison of Microglial PET Imaging in Parkinson’s Disease, RBD, and Controls with a CSF1R and TSPO Ligand.
Objective: To compare regional binding patterns of microglial PET radioligands: [11C]DPA-713, a TSPO ligand, and [11C]CPPC1, a CSF1R ligand in people with Parkinson’s disease (PD).…Dopaminergic and Synaptic Alterations in SWEDD: Insights from [¹⁸F] FE-PE2I and [¹¹C] UCB-J PET Imaging
Objective: To investigate dopaminergic and synaptic density in SWEDD patients compared to idiopathic Parkinson’s disease (IPD) and healthy controls (HCs). Background: Scans Without Evidence of…Alterations in Basal Ganglia Synaptic Density and Thalamic Gray Matter Volume are associated with Motor Signs in Late Life Depression: an 11C-UCB-J PET/MR study.
Objective: To investigate differences in the association of motor signs with synaptic density, gray matter volume and white matter lesion volume in patients with late…Functional Segregation in Parkinson’s Disease
Objective: We assessed patterns of dopamine (DA) release and striatal activation induced by behavioural tasks involving corticostriatal loops in Parkinson’s disease (PD) and healthy control…Longitudinal FDG-PET Study of Metabolic Trajectories and Connectivity Alterations in Multiple System Atrophy
Objective: 本研究使用 FDG-PET 探索 MSA 中葡萄糖代谢和网络连接的纵向变化，以辅助早期诊断和监测疾病进展。 Background: Multiple system atrophy (MSA) is a rapidly progressive neurodegenerative disease with distinct metabolic patterns in its parkinsonian (MSA-P)…Clinical Profile and 18F -Fluorodopa Positron Emission Tomography (18F -DOPA PET) Findings in a Movement Disorder Clinic Patient Cohort
Objective: This study aimed to evaluate the utility of 18F -DOPA PET in patients with diagnostic uncertainty at our movement disorder clinic in India. Background:…PET and Clinical Evidence for Neuroprotective Effects of KM-819 on MSA
Objective: To assess the effect of KM-819 on the progression of multiple system atrophy (MSA). Background: Parkinson’s brain is associated with increased expression of the…
