Embodiments of the present disclosure provide compositions and methods for performing positron emission tomography (PET) and, more particularly, to compositions and methods for the development and use of 18F-based PET tracers for use in selected imaging techniques such as studies of myocardial physiology. In particular, as disclosed herein, at tracer levels, [18F]F-AraG has the ability to be used in a number of new PET methodologies including those designed for cardiac and/or mitochondrial activity imaging. The use of [18F]F-AraG as a PET tracer offers significant advantages over conventional 18F labeled tracers in a number of distinct applications including observations of selected physiological phenomena such as myocardial perfusion, myocardial viability, and heart inflammation. Methods of the invention include those designed to use [18F]F-AraG to observe patient physiological responses to various therapeutic agents, as well as using [18F]F-AraG as a PET tracer in drug development studies.
本公开的实施例提供了用于执行正电子发射断层扫描(PET)的组合物和方法,更具体地,提供了用于开发和使用18F基PET示踪剂的组合物和方法,用于选择成像技术,如心肌生理研究。特别地,在示踪剂
水平上,[18F]F-AraG具有能够用于许多新的PET方法,包括那些设计用于心脏和/或线粒体活性成像的能力。使用[18F]F-AraG作为PET示踪剂在许多不同应用中比传统的18F标记示踪剂具有显著优势,包括观察选择的生理现象,如心肌灌注、心肌存活和心脏炎症。本发明的方法包括那些旨在使用[18F]F-AraG观察患者对各种治疗剂的生理反应,以及将[18F]F-AraG用作PET示踪剂进行药物开发研究的方法。
