DESCRIPTION (provided by applicant): The goal of this proposal is to make a state-of-the-art ultrasound imaging system available for NIH-funded researchers at the University of Wisconsin (UW) Medical School. The Section of Cardiovascular Medicine and the UW Department of Population Health Sciences have a strong history of successful and productive collaborations that have resulted in high-quality research in cardiology and the epidemiology of cardiovascular disease. Acquisition of an ultrasound imaging system will facilitate and significantly enhance the scientific quality of several ongoing NIH-supported research projects described in this grant application. The Siemens Acuson Sequoia C512 is a state-of-the-art, multipurpose instrument for cardiac and vascular ultrasound imaging. All of the funded research studies for which we are seeking a shared ultrasound system will use it as a tool to better understand the physiological consequences of sleep-disordered breathing, hypertension, diabetes mellitus, congestive heart failure, and myocardial infarction. The three "major" users are an ideal group to share instrumentation given their common research interests in sleep-disordered breathing and cardiovascular disease, their need for high-quality ultrasound to assess cardiovascular structure and function, their strong collaborative relationships with the Principal Investigator, and their status as active, R01-funded investigators. All six investigators use several ultrasound-based research techniques including the evaluation of carotid intima-media thickness, brachial artery reactivity, cerebral blood flow, coronary blood flow, and left ventricular systolic and diastolic function. Because diagnostic ultrasound has no known biological effects, serial studies can be performed longitudinally to evaluate various stages of disease processes and their responses to interventions. Since the research equipment needed to perform these studies currently does not exist in the UW Medical School, it must be borrowed or time purchased from an already oversubscribed clinical laboratory, an expensive and inconvenient arrangement. The necessary space, administrative support, supervision, and technical expertise already are in place to assure that the requested equipment will be operable immediately and highly productive at UW. There is significant opportunity for greater collaboration, research productivity, and cost savings if an ultrasound system is made available at the UW Medical School as a shared resource.

描述（由申请人提供）： 该提案的目标是为威斯康星大学 (UW) 医学院的 NIH 资助研究人员提供最先进的超声成像系统。心血管医学科和威斯康星大学人口健康科学系有着悠久的成功和富有成效的合作历史，在心脏病学和心血管疾病流行病学方面取得了高质量的研究成果。采购超声成像系统将促进并显着提高本拨款申请中描述的几个正在进行的 NIH 支持的研究项目的科学质量。西门子 Acuson Sequoia C512 是一款最先进的多功能心脏和血管超声成像仪器。我们正在寻求共享超声系统的所有资助研究都将使用它作为工具，以更好地了解睡眠呼吸障碍、高血压、糖尿病、充血性心力衰竭和心肌梗塞的生理后果。三个“主要”用户是共享仪器的理想群体，因为他们对睡眠呼吸障碍和心血管疾病有共同的研究兴趣，他们需要高质量的超声来评估心血管结构和功能，他们与首席研究员的牢固合作关系，以及他们作为 R01 资助的活跃调查员的地位。所有六名研究人员均使用多种基于超声的研究技术，包括评估颈动脉内膜中层厚度、肱动脉反应性、脑血流量、冠状血流量以及左心室收缩和舒张功能。由于诊断超声没有已知的生物效应，因此可以纵向进行系列研究，以评估疾病过程的各个阶段及其对干预措施的反应。由于华盛顿大学医学院目前不存在进行这些研究所需的研究设备，因此必须从已经超额认购的临床实验室借用或花时间购买，这是一种昂贵且不方便的安排。必要的空间、行政支持、监督和技术专业知识已经到位，以确保所需的设备能够在威斯康星大学立即投入使用并保持高生产率。如果威斯康星大学医学院将超声系统作为共享资源提供，那么将有很大的机会实现更大的合作、研究生产力和节省成本。
