DESCRIPTION (provided by applicant): Center for Magnetic Resonance Research at the University of Minnesota is an interdepartmental and interdisciplinary research laboratory that has been funded as a Biotechnology Research Resource (BTRR) during the last nine years. The central research focus of this BTRR is development and improvement of methodologies and technologies for high magnetic resonance (MR) imaging and spectroscopy, and providing state-of-the-art instrumentation, expertise and infrastructure to enable the faculty, trainees and staff of several institutions in the USA and abroad to carry out basic and applied biomedical research that utilizes these unique high magnetic field (4 to 9.4 Tesla) capabilities. The general aim of this application is to seek continued support for this Biomedical Technology Research Resource so as to pursue new methodological and technical developments and maintain a National Research Resource with unique instrumentation and expertise that is not readily available elsewhere. A central and primary aim of the Core projects is to develop techniques for obtaining simultaneous information on aspects of organ function, perfusion, oxygen extraction, metabolism, and anatomy in humans non-invasively, using the unique advantages provided by high magnetic fields, such as the high signal-to-noise ratio, increased susceptibility effects associated with blood for imaging brain function, longer Tls for measurement of tissue perfusion, increased chemical-shift resolution for improved detection of neurochemicals, and the use of magnetic isotopes of biologically active atoms, such as O-17, which are not accessible easily at low magnetic fields due to their low gyromagnetic ratio. These techniques have been and will continue to be utilized to support a large community of NIH funded researchers working in neurosciences, functional brain mapping, brain metabolism, metabolic disorders, and cardiac pathology and bioenergetics.

描述(由申请人提供)： 明尼苏达大学磁共振研究中心是一个跨部门和跨学科的研究实验室，在过去的九年中作为生物技术研究资源(BTRR)得到了资助。BTRR的中心研究重点是开发和改进用于高磁共振(MR)成像和光谱分析的方法和技术，并提供最先进的仪器、专业知识和基础设施，使美国和国外几个机构的教职员工、学员和工作人员能够利用这些独特的强磁场(4至9.4特斯拉)能力开展基础和应用生物医学研究。这项申请的总体目标是寻求对这一生物医学技术研究资源的持续支持，以追求新的方法和技术发展，并保持一个拥有独特仪器和专业知识的国家研究资源，这是其他地方无法轻易获得的。核心项目的一个中心和主要目标是开发技术，以非侵入性地获得有关人体器官功能、血流灌注、氧气提取、新陈代谢和解剖学方面的同步信息，利用强磁场提供的独特优势，例如高信噪比、增加与血液相关的敏感性效应用于脑功能成像、延长TLS用于测量组织灌注、提高化学位移分辨率以改进神经化学物质的检测，以及使用具有生物活性的原子的磁性同位素，如O-17，由于其低旋磁比，在低磁场下不易接触到。这些技术已经并将继续用于支持NIH资助的一大批研究人员，他们从事神经科学、脑功能图谱、大脑代谢、代谢紊乱以及心脏病理学和生物能量学方面的工作。
