DESCRIPTION (provided by applicant): This grant is to support the acquisition of a high-field small animal imager to support multiple NIH- funded investigators using small animals for biomedical research. The imager selected is a 7T Bruker ClinScan system which incorporates the advantages of Bruker magnet, gradient coil and radiofrequency coil with the expertise and accomplishments of Siemens Medical Solutions to produce the RF electronics and controlling software. That the new imager will operate using syngo software which is the same as used on the Siemens TIM Trio also housed in the Magnetic Resonance Imaging and Spectroscopy Center (MRISC) will facilitate translation of imaging protocols between experimental animals and human research subjects and will aid in the acquisition of optimal imaging protocols on complex studies. The instrument will be installed in and administered by MRISC - a university core facility dedicated to the development of innovative preclinical and experimental MR imaging of experimental animals and humans. The imager will be operated and maintained by a group of experienced MR researchers. The imager will be sited next to the animal colony facility which houses non-human primates, as well as rats and mice used for a variety of research studies. PUBLIC HEALH RELEVANCE: This High End Instrumentation Grant will provide a high field, MR imager suitable for small animal in vivo imager to a multi-user group of productive, NIH-funded, biomedical researchers. This instrument will replace the current use of a clinical imager, ill suited for imaging rodents, with a state-of-the-art, high field imager suitable for research into traumatic injury, cancer, cardiovascular and several other areas of research currently underway at the University of Kentucky.

描述（由申请人提供）：这笔赠款用于支持购买高场小动物成像仪，以支持 NIH 资助的多名研究人员使用小动物进行生物医学研究。所选择的成像仪是 7T Bruker ClinScan 系统，该系统结合了 Bruker 磁铁、梯度线圈和射频线圈的优点以及西门子医疗解决方案的专业知识和成就，以生产射频电子设备和控制软件。新成像仪将使用 syngo 软件进行操作，该软件与同样位于磁共振成像和光谱中心 (MRISC) 的西门子 TIM Trio 上使用的软件相同，将有助于实验动物和人类研究对象之间成像协议的转换，并有助于在复杂研究中获取最佳成像协议。该仪器将安装在 MRISC 中并由 MRISC 管理，MRISC 是一所大学核心设施，致力于开发实验动物和人类的创新临床前和实验 MR 成像。该成像仪将由一组经验丰富的 MR 研究人员操作和维护。该成像仪将安装在动物群落设施旁边，该设施饲养着非人类灵长类动物以及用于各种研究的大鼠和小鼠。 公共健康相关性：这项高端仪器拨款将为 NIH 资助的多用户多用户群体提供适用于小动物活体成像仪的高场 MR 成像仪、生物医学研究人员。该仪器将取代目前使用的不适合对啮齿动物进行成像的临床成像仪，采用最先进的高场成像仪，适用于外伤、癌症、心血管和肯塔基大学目前正在进行的其他几个研究领域的研究。
