Imaging Archive for Magnetic Resonance Imaging Systems

描述(由申请人提供)：A.A.Martinos生物医学成像中心(前身为MGH-核磁共振中心)对用于存储和检索成像数据的档案系统的需求日益增长。该中心的四(4)个活跃的人体研究核磁共振扫描仪和三(3)个动物系统由100多个不同的用户使用，每个用户都负责将自己的数据存档。这些用户中的大多数人的背景不是放射科学，因此不习惯数据存档的详细要求。正因为如此，尽管进行了广泛的培训和努力，数据丢失还是太常见了，在一些调查人员中，丢失数据的比例可能在1%到3%之间。一个安全、冗余的存档系统与放射信息系统(RIS)相结合，可以防止这种损失。除了这一需要，一些目前得到资助的项目将从科学上受益于编目的档案，该档案允许在适当的人体研究指导方针下进行回溯性分析。例如，一位使用功能磁共振成像进行大脑成像的神经科学家可能会了解到一种新的分析技术，并希望使用新工具重新分析两年的数据。中央档案使检索数据以检验这一假设的任务变得切实可行。此外，进行多中心临床研究所需的技术分析将通过这样的档案/RIS组合来促进。这些分析包括确保扫描仪稳定性的研究内比较、扫描仪技术参数的测量，如一天中时间对扫描仪噪声的影响、新软件或硬件升级对图像质量的影响。我们建议的RIS系统还可以在扫描中央存档和检索时存储扫描的同意书和其他数据，所有这些都具有复杂的访问控制。这种工具在协助调查人员保持完全遵守《HIPAA》方面也大有裨益，特别是在这种隐私要求的解释随着时间的推移而被修改的情况下。例如，某些体积核磁共振扫描的质量足够高，可以识别受试者的面部，这可能违反隐私规则。中央档案将为我们提供一个通用平台，使所需的隐私工具/协议自动化，从而使我们的中心能够向希望关注科学而不是图像存储细节的用户社区提供完全符合HIPAA的服务。总体而言，这种所需的资源将极大地便利许多NIH资助的调查人员和未来几年的调查。

DESCRIPTION (provided by applicant): The A.A. Martinos Center for Biomedical Imaging (formerly known as the MGH-NMR Center), has an acute and growing need for an archival system for storage and retrieval of imaging data. The Center's four (4) active human research MRI scanners and three (3) animal systems are used by over 100 different users, each of whom is responsible for archiving their own data. Most of these users have backgrounds that are not in the radiological sciences, and are therefore not accustomed to the detailed requirements for data archiving. Because of this, despite extensive training and efforts, data loss is all too common, perhaps 1% to as much as 3% among some investigators. A secure, redundant archiving system coupled with a radiology information system (RIS) could prevent such loss. In addition to this need, a number of currently funded projects would scientifically benefit from a cataloged archive that allows, under appropriate human studies guidelines, retrospective analyses. For example, a neuroscientist using fMRI to do brain mapping may learn of a new analysis technique and wish to re-analyze two year's worth of data using the new tool. A central archive makes the task of retrieving data to test such a hypothesis practical. Furthermore, technical analyses needed to undertake multicenter clinical studies would be facilitated by such an archive/RIS combination. Such analyses include intra-study comparison across time points to ensure scanner stability, measurements of technical scanner parameters such as the effect of time of day on scanner noise, effect of new software or hardware upgrades on image quality. The RIS system we propose could also store scanned-in consent forms and other data at the time of scanning for central archiving and retrieval, all with sophisticated access controls. Such a tool would also be highly beneficially in assisting investigators in maintaining full HIPAA compliance, especially as interpretations of such privacy requirements are modified over time. For example, certain volumetric MRI scans are of high enough quality that a subject's face is recognizable, a potential violation of privacy rules. A central archive would provide a common platform for us to automate needed privacy tools/protocols, thereby allowing our Center to offer fully HIPAA-compliant services to a user community that wishes to focus on science, not on the details of image storage. Overall, this needed resource will greatly facilitate many NIH-funded investigators and investigations for years to come.
