Objective: To examine correlations between in vivo positron emission tomography (PET) imaging with 18F-PM-PBB3 (18F-florzolotau) and postmortem neuropathological findings in a patient with progressive supranuclear palsy (PSP).Background: There have been no reports demonstrating tight PET-pathology ...
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...
而18F-APN-1607(18F-PM-PBB3)在临床研究中被发现存在脉络丛摄取[8],且其在制备过程中需要避光保存,使用较为复杂,这些脱靶结合会影响到海马区域的定量结果。18F-MK6240与MAO-B结合较低,且没有基底节区及脉络丛的非特性摄取,在研究...
[18F]PM-PBB3 or [18F]APN-1607, Fig. 1C) has shown promise to detect tau accumulation typical of PSP pathophysiology; however, longitudinal follow-up studies are necessary to determine whether [18F]florzolotau can be a reliable diagnostic tool for PSP27. [18F]Florzolotau also showed uptake...
The first-generation tau PET tracers, such as [11C]PBB3, [18F]AV1451, and [18F]THK5351, have shown accu- mulation in the predilection site for tau deposition. Tau PET imaging recapitulated topographical re- gional distribution patterns similar to those reported by Braak staging of tau ...
