Amyloid PET imaging in multiple sclerosis: an 18F-florbetaben study
BACKGROUND Positron emission tomography (PET) images with amyloid tracers show normal uptake in healthy white matter, which suggests that amyloid tracers are potentially useful for studying such white matter diseases as multiple sclerosis (MS). METHODS Twelve patients diagnosed with MS (5 with RRMS, 5 with SPMS, and 2 with PPMS) and 3 healthy controls underwent studies with MRI and (18)F-flor...
متن کاملCardiac Amyloid Imaging with 18F-Florbetaben PET: A Pilot Study.
Our aim was to determine the feasibility of 18F-florbetaben PET in diagnosing cardiac amyloidosis. METHODS 18F-florbetaben PET was performed on 14 patients: 5 amyloid light chain, 5 amyloid transthyretin, and 4 control with hypertensive heart disease. Qualitative and quantitative assessments of 18F-florbetaben activity were performed using the SUVmean of the left ventricular myocardium and bl...
متن کاملCross-Sectional Comparison of Small Animal [18F]-Florbetaben Amyloid-PET between Transgenic AD Mouse Models
We aimed to compare [18F]-florbetaben PET imaging in four transgenic mouse strains modelling Alzheimer's disease (AD), with the main focus on APPswe/PS2 mice and C57Bl/6 mice serving as controls (WT). A consistent PET protocol (N = 82 PET scans) was used, with cortical standardized uptake value ratio (SUVR) relative to cerebellum as the endpoint. We correlated methoxy-X04 staining of β-amyloid ...
متن کاملOptimization of Brain Tumor MR Image Classification Accuracy Using Optimal Threshold, PCA and Training ANFIS with Different Repetitions
Background: One of the leading causes of death is brain tumors. Accurate tumor classification leads to appropriate decision making and providing the most efficient treatment to the patients. This study aims to optimize brain tumor MR images classification accuracy using optimal threshold, PCA and training Adaptive Neuro Fuzzy Inference System (ANFIS) with different repetitions.Material and Meth...
متن کاملWhole Brain Voxel-Wise Analysis of Cerebral Retention of Beta-Amyloid in Cognitively Normal Older Adults Using 18F-Florbetaben
Objective Recently developed 18F-labelled amyloid beta (Aβ) positron emission tomography (PET) tracers have demonstrated potentials to enable more prevalent application of amyloid imaging in the clinical setting. The aim of this study is to demonstrate cerebral retention of Aβ in cognitively normal older adults, by implementing voxel-based analysis on images acquired from 18F-Florbetaben amyloi...
