    The present invention generally relates to methods and system for the synthesis of imaging agents, and precursors thereof. The methods may exhibit improved yields and may allow for the large-scale synthesis of imaging agents, including imaging agents comprising a radioisotope (e.g., 18F). Various embodiments of the invention may be useful as sensors, diagnostic tools, and the like. In some cases, methods for evaluating perfusion, including myocardial perfusion, are provided. Synthetic methods of the invention have also been incorporated into an automated synthesis unit to prepare and purify imaging agents that comprise a radioisotope. In some embodiments, the present invention provides a novel methods and systems comprising imaging agent 1, including methods of imaging in a subject comprising administering a composition comprising imaging agent 1 to a subject by injection, infusion, or any other known method, and imaging the area of the subject wherein the event of interest is located.
    本发明一般涉及成像剂及其前体的合成方法和系统。这些方法可提高产量,并可大规模合成成像剂,包括包含放射性同位素(如 18F)的成像剂。本发明的各种实施方案可用作传感器、诊断工具等。在某些情况下,本发明提供了评估灌注(包括心肌灌注)的方法。本发明的合成方法也已纳入自动合成装置,用于制备和纯化包含放射性同位素的成像剂。在一些实施方案中,本发明提供了一种包含成像剂 1 的新型方法和系统,包括在受试者中成像的方法,包括通过注射、输注或任何其他已知方法向受试者施用包含成像剂 1 的组合物,并对受试者感兴趣事件所在区域成像。
