The developed model was capable of automatically and accurately classifying brain PET scans as amyloid positive or negative without relying on experienced readers or requiring structural MRI. 开发的模型能够自动且准确地将脑PET扫描分类为淀粉样阳性或阴性,而无需依赖有经验的读者或结构性MRI。 Results 结果 T...
The PET image is generated from a radiotracer binding to amyloid brain plaque. A cortical profile is generated from the PET image. The cortical profile describes cortical tracer uptake to varying projection depths inside the cortex of the brain. The PET image is quantitatively assessed using the ...
“By acquiring an amyloid imaging scan within a month of the indeterminate FDG-PET, managing physicians can treat patients with anAlzheimer’s-like pattern of reduced brain metabolism with a better chance of preserving cognitive ...
Moreover, this study investigated the natural history of functional impairment depending on the initial amyloid load in the brain. Nevertheless, direct associations between amyloidosis and future functional decline cannot be drawn from the current study. One may assume that the effects of amyloid load...
Amyloid (Aβ) levels in the brain may be detected by positron emission tomography (PET) using a ligand such as florabetaben that binds to amyloid plaques and that can be labeled with a positron-emitting isotope (18F). PET scans can thus quantify both the degree of binding and the location...

As reported previously [29], a critical criterion for inclusion was that a measure of brain amyloid load was available, using either CSF Aβ or amyloid PET scan. The classification of amyloid burden (high/low) in the EMIF-AD MBD cohort has been described previously [29]. Furthermore, Aβ...

CSF (and blood-based) biomarkers provide somewhat different information from Aβ-PET, with the latter showing the brain regional distribution of Aβ. In contrast, the former allows the simultaneous investigation of different pathophysiological mechanisms other than brain Aβ accumulation [299, 318, ...
