在初步分析中,检测[18F] flortaucipir的辨别准确性(即敏感性和特异性)AD痴呆与所有非AD神经退行性疾病。在二次分析中,将[18F] flortaucipir SUVR的曲线下面积(AUC)与3个建立的磁共振成像测量值(海马体积和AD特征和全脑皮质厚度)以及[18F] flortaucipir的敏感性和特异性进行比较。在MCI中由于AD与非AD...
The tau positron emission tomography (PET) ligand 18F-flortaucipir binds to paired helical filaments of tau in aging and Alzheimer's disease (AD), but its utility in detecting tau aggregates in frontotemporal dementia (FTD) is uncertain.We performed 18F-flortaucipir imaging in patients with ...
FDA)批准的18F-flortaucipir (AV-1451)[3],在临床研究中发现与健康老年受试者存在非特异性结合[4-5],其与单胺氧化酶(monoamine oxidase, MAO-B) 的非特异性摄取[6-7]以及与基底节和脉络丛非靶结合,限制了其使用前景。而
现有的tau蛋白示踪剂,如18F-flortaucipir (AV-1451)、 18F-APN-1607(18F-PM-PBB3)等出现了较多脱靶结合的报道[3-9]。18F-MK6240作为新一代示踪剂,表现出较强的灵敏度和特异性,在体内外研究中均表现出较强的靶区结合,且在脑内没有非特异性结合[10],应用前景良好。本研究旨在利用18F-MK6240作为tau蛋白...
目前,在tau蛋白示踪剂研发过程中出现的重要问题之一是存在脱靶结合,美国食品与药品监督管理局(Food and Drug Administration, FDA)批准的18F-flortaucipir (AV-1451)[3],在临床研究中发现与健康老年受试者存在非特异性结合[4-5],其与单胺氧化酶(monoamine oxidase, MAO-B) 的非特异性摄取[6-7]以及与基底节...
