Abstract

Because carbon-11 (11C) radiotracers cannot be shipped over long distances, their use in routine positron emission tomography (PET) studies is dependent on the production capabilities of individual radiochemistry laboratories. Since 2003, 11C-labeled Pittsburgh compound B ([11C]PiB) has been the gold standard PET radiotracer for in vivo imaging of amyloid β (Aβ) plaques. For more than two decades, researchers have been working to develop faster, higher-yielding, more robust, and optimized production methods with higher radiochemical yields for various imaging applications. This review evaluates progress in [11C]PiB radiochemistry. An introductory overview assesses how it has been applied in clinical neurologic imaging research. We examine the varying approaches reported for radiolabeling, purification, extraction, and formulation. Further considerations for QC methods, regulatory considerations, and optimizations were also discussed.

2003-2023 年[11C]PiB 合成二十年:回顾。
由于碳-11(11C)放射性示踪剂无法远距离运输,因此其在常规正电子发射断层扫描(PET)研究中的应用取决于各个放射化学实验室的生产能力。自 2003 年以来,11C 标记的匹兹堡化合物 B([11C]PiB)一直是淀粉样β(Aβ)斑块体内成像的黄金标准 PET 放射性示踪剂。二十多年来,研究人员一直致力于为各种成像应用开发更快、更高产、更稳健、更优化的生产方法,以及更高的放射化学产率。本综述评估了 [11C]PiB 放射化学的进展。介绍性概述评估了其在临床神经成像研究中的应用情况。我们研究了已报道的放射标记、纯化、提取和配制的不同方法。此外,还讨论了质量控制方法、监管注意事项和优化方面的进一步考虑。

期刊介绍: The scope of AJNMMI encompasses all areas of molecular imaging, including but not limited to: positron emission tomography (PET), single-photon emission computed tomography (SPECT), molecular magnetic resonance imaging, magnetic resonance spectroscopy, optical bioluminescence, optical fluorescence, targeted ultrasound, photoacoustic imaging, etc. AJNMMI welcomes original and review articles on both clinical investigation and preclinical research. Occasionally, special topic issues, short communications, editorials, and invited perspectives will also be published. Manuscripts, including figures and tables, must be original and not under consideration by another journal.
