Utility of FDG PET/CT in assessing bowel inflammation

This study found a significant correlation between age and average FDG uptake (avg-SUV) of the GI tract (P=.0003) with the esophagus showing the highest significance. Correlations were found between avg-SUV of the sigmoid segment and the group average (P

AbstractPurposeOur aim in this study was to compare different non-invasive pharmacokinetic models and assess test –retest reproducibility of the radioligand [11C]SCH23390 for the quantification of dopamine D1-like receptor (D1R) in both wild-type (WT) mice and heterozygous (HET) Q175DN mice as Huntington ’s disease (HD) model.ProceduresAdult WT (n = 9) and HET (n = 14) mice underwent a 90-min [11C]SCH23390 positron emission tomography (PET) scan followed by computed tomography (CT) to evaluate the pharmacokinetic modelling in healthy and diseased conditions. Additionally, 5 WT mice a...

Metabotropic glutamate receptor 5 (mGluR5) represents a potential therapeutic target for Huntington disease. Using 11C-ABP688 (3-(6-methyl-pyridin-2-ylethynyl)-cyclohex-2-enone-O-11C-methyl-oxime), a noncompetitive and highly selective antagonist for mGluR5, we aimed to longitudinally characterize in vivo changes in mGluR5 by means of PET imaging in the Q175 mouse model of Huntington disease. Methods: 11C-ABP688 PET imaging, followed by a CT scan, was performed on 18 heterozygous mice and 18 wild-type (WT) littermates at 3 different time points (6, 9, and 13 mo old). 11C-ABP688 nondisplaceable binding potential (BPND) was ...

In this study, we utilized an imaging-based assay to monitor the ability of disease-associated amyloid assemblies to rupture intracellular vesicles following endocytosis. We observe that the ability to induce vesicle rupture is a common feature of α-synuclein (α-syn) assemblies, as assemblies derived from wild type (WT) or familial disease-associated mutant α-syn all exhibited the ability to induce vesicle rupture. Similarly, different conformational strains of WT α-syn assemblies, but not monomeric or oligomeric forms, efficiently induced vesicle rupture following endocytosis. The ability to...

Conclusions:This case is unique in that RCC is rarely associated with chorea or LGI-1 antibodies and removal of the tumor led to symptom resolution.Disclosure: Dr. Colletta has nothing to disclose. Dr. Kartha has nothing to disclose. Dr. Ruland has nothing to disclose.

We reported a 24-year-old woman who developed a movement disorder of mouth and limbs during systemic lupus erythematosus. Brain MRI did not find any abnormalities. Increased FDG uptake in basal ganglia was found using FDG PET/CT brain scan. The symptoms remitted after therapy and the activities of the original hypermetabolic regions were down to normal in the follow-up FDG PET/CT scan. This case implies that the pathophysiology of chorea in systemic lupus erythematosus is different from that of chorea in other diseases, such as Huntington disease and chorea-acanthocytosis, in which hypometabolic basal ganglia was found.
