A High Field (7T) Whole Body MR Research System

描述（由申请人提供）：磁共振（MR）在医学中的应用已经看到磁体场强的稳定增长。 这种增长在最近FDA批准用于常规临床应用的3特斯拉系统中得到了部分证明。 场强持续提高的原因有很多，它们有助于支持这种方法对改进生物医学研究的重要性。 在本提案中，我们要求资金协助购买7特斯拉全身研究MR系统。 该系统由超导磁体、控制台、射频电子设备、梯度、梯度电源和临床MRI单元上常见的所有其他相关设备（例如床、护罩、受试者定位电子设备、受试者通信设备等）组成。 该系统的安装、调试和服务将由Siemens Medical负责。 西门子承诺将投入大量的财力和人力资源，包括一名全职工程师和一名全职项目经理。 此外，西门子将与纽约大学放射科工作人员密切合作，确保系统的持续支持和运行。 在这方面，纽约大学还将支付并维持与西门子就该系统签订的服务合同。 纽约大学医学中心最近开始了一项实质性的研究计划，其中包括建立一个最先进的磁共振成像（MRI）和光谱（MRS）中心。 这里要求的7特斯拉系统将用于支持来自NYUMC及其合作机构的几个PHS支持的调查人员。

DESCRIPTION (provided by applicant): The application of Magnetic Resonance (MR) in medicine has seen a steady growth in the field strength of the magnets. This growth is partially evident from recent FDA approval of 3 Tesla systems for routine clinical applications. The reasons for this continued advance in field strength are many, and they serve to support the significance of this approach to improved biomedical research. In this proposal we are requesting funds to assist in the purchase of a 7 Tesla whole-body research MR system. The system consists of a superconducting magnet, console, RF electronics, gradients, gradient power supplies, and all other associated equipment normally found on a clinical MRI unit (e.g. bed, shroud, subject positioning electronics, subject communication devices, etc.). The installation, commissioning, and service of this system will be the responsibility of the Siemens Medical. Siemens has pledged to devote significant financial and personnel resources to this site including a full time engineer and a full time project manager. In addition, Siemens will work closely with NYU radiology staff to ensure the systems continued support and operation. In this regard, NYU will also pay for and maintain a service contract with Siemens for this system. New York University Medical Center has recently embarked on a substantial research program initiative that includes the establishment of a state-of-the-art Magnetic Resonance Imaging (MRI) and Spectroscopy (MRS) center. The 7 Tesla system requested here, will be used to support several PHS supported investigators from NYUMC and its collaborative institutions.
