DESCRIPTION (provided by applicant): The broad, long-term objective of this proposal is to better understand the fundamental biology that underlies human diseases, and to improve diagnostics and therapeutics for cancer, cardiovascular diseases, reproductive disorders, acute lung injury, orthopedic defects and rheumatoid arthritis. There is currently no preclinical in vivo radionuclide imaging or CT capability at Northwestern University. Funds are requested for the purchase of a preclinical SPECT/CT scanner dedicated to small animal imaging studies. The scanner will play a vital role in supporting basic and preclinical research activities from multipl NIH-funded Program Projects (PPGs) and Investigator-Initiated Projects at Northwestern University. The imaging capabilities offered by the scanner will enable measurements that are otherwise difficult or impossible to obtain using alternative methods. The scanner will help bring studies from a molecular/cellular level to a system level, and provide preclinical validations for clinical translation. The availability of this scanner will also foster new collaborations and spur imaging technology development. The strengths of radionuclide imaging include sensitivity, quantifiable data, and depth of signal penetration in tissues. These features make it suitable for studying molecular events at physiologically relevant levels. Radionuclide imaging utilities that will benefit current research projects include advanced molecular imaging, biomarker development, tracer kinetics, dosimetry, and functional imaging. The CT module provides anatomical information for assisting data analysis in radionuclide imaging studies. As a stand-alone imaging technique, CT is an indispensable tool for characterizing hard tissues and other X-ray-opaque materials in terms of morphometric measurements. Overall, techniques offered by the preclinical SPECT/CT scanner will enable quantitative, noninvasive and longitudinal measurements that address the technological needs and enhance the advancements of a wide range of biomedical research projects. To accommodate this instrument, the University has made concrete commitments in terms of financial support, imaging expertise, management team, operational staff and infrastructure. The scanner will become an important component at the existing multimodality imaging core facility at Northwestern University.

描述（由申请人提供）：该提案的广泛、长期目标是更好地了解人类疾病的基础生物学，并改进癌症、心血管疾病、生殖障碍、急性肺损伤、骨科缺陷的诊断和治疗和类风湿性关节炎。目前尚无临床前体内 西北大学的放射性核素成像或 CT 能力。需要资金购买专用于小动物成像研究的临床前 SPECT/CT 扫描仪。该扫描仪将在支持西北大学多个 NIH 资助的项目 (PPG) 和研究者发起的项目的基础和临床前研究活动中发挥至关重要的作用。扫描仪提供的成像功能将能够实现使用其他方法很难或不可能获得的测量结果。该扫描仪将有助于将研究从分子/细胞水平提升到系统水平，并为临床转化提供临床前验证。该扫描仪的推出也将促进新的合作并刺激 成像技术的发展。放射性核素成像的优势包括灵敏度、可量化数据和信号在组织中的穿透深度。这些特征使其适合研究生理相关水平的分子事件。将使当前研究项目受益的放射性核素成像实用程序包括先进的分子成像、生物标志物开发、示踪动力学、剂量测定和功能成像。 CT 模块提供解剖信息，以协助放射性核素成像研究中的数据分析。作为一种独立的成像技术，CT 是在形态测量方面表征硬组织和其他 X 射线不透明材料的不可或缺的工具。总体而言，临床前 SPECT/CT 扫描仪提供的技术将实现定量、无创和纵向测量，满足技术需求并促进广泛的生物医学研究项目的进步。为了适应该仪器，大学在财政支持、成像专业知识、管理团队、操作人员和基础设施方面做出了具体承诺。该扫描仪将成为西北大学现有多模态成像核心设施的重要组成部分。
