该技术通过注射特殊的放射性示踪剂(如Florbetapir、Florbetaben或Flutemetamol),利用PET扫描设备清晰地显示脑部的Amyloid沉积情况。Amyloid的异常积聚是阿尔茨海默病(Alzheimer's Disease,AD)的一个重要特征。用途:1. 早期诊断阿尔茨海默病:Amyloid ...
Purpose目的To develop a deep learning model to classify minimally processed brain PET scans as amyloid positive or negative, evaluateits performance on independent data sets and different tracers, and compare it with human visual reads.为了开发一个深度学习模型来对最小处理过的大脑PET扫描进行分类(阿尔...
Amyloid PET显像是一种用于检测人脑中β淀粉样蛋白(Amyloid-β)沉积的核医学影像技术。该技术通过注射特殊的放射性示踪剂(如Florbetapir、Florbetaben或Flutemetamol),利用PET扫描设备清晰地显示脑部的Amyloid沉积情况。Amyloid的异常积聚是阿尔茨海默病(Alzheimer's Disease,AD)的一个重要特征。 用途: 1.早期诊断阿尔茨海默...

AD的临床试验通常需要异常的amyloid生物标记物。本文中，阳性的Aβ和tau的 PET与无阳性的tau和Aβ扫描相比，认知功能未受损向MCI进展的风险高7至29倍。这些结果表明：(1)Aβ的存在通常是检测tau- pet示踪剂结合的先决条件；(2)tau病理对于即将到来的衰退至关重要。因此，结合tau和Aβ PET大大提高了与临床前...
In the latest revised criteria for the diagnosis of AD biomarkers were defined and integrated: pathological and diagnostic biomarkers (increased retention on fibrillar amyloid PET or decreased A尾1-42 and increased T-Tau or P-Tau in CSF) and neurodegeneration or topographical biomarkers (temporo...
Amyloid-PET was assessed continuously on the Centiloid (CL) scale and using Aβ groups (CL < 12 = Aβ-, 12 ≤ CL ≤ 50 = Aβ-intermediate/Aβ± , CL > 50 = Aβ+). Functional abilities were longitudinally assessed using the Clinical Dementia Rating...
