COMPLETE INTRACRANIAL ARTERIAL AND VENOUS BLOOD FLOW EVALUATION WITH 4D FLOW MRI

这个子项目是许多利用资源的研究子项目之一 由NIH/NCRR资助的中心拨款提供。子项目的主要支持 而子项目的主要调查员可能是由其他来源提供的， 包括其它NIH来源。 列出的子项目总成本可能 代表子项目使用的中心基础设施的估计数量， 而不是由NCRR赠款提供给子项目或子项目工作人员的直接资金。 时间分辨、3D速度编码MR成像（4D Flow）允许采集动态、多向血流 数据，最近已被用于评价颅内动脉血流。使用3 T系统，同时优化 时间分辨率和k空间子采样，结合并行成像和切角采集， 通过提供完整的颅内动脉， 扫描时间为677次心跳。 要了解卢卡斯中心正在进行的其他项目，请访问http://rsl.stanford.edu/ （卢卡斯年度报告和 ISMRM 2011摘要）

This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. Primary support for the subproject and the subproject's principal investigator may have been provided by other sources, including other NIH sources. The Total Cost listed for the subproject likely represents the estimated amount of Center infrastructure utilized by the subproject, not direct funding provided by the NCRR grant to the subproject or subproject staff. Time-resolved, 3D velocity-encoded MR imaging (4D Flow) allows for the acquisition of dynamic, multidirectional blood flow data, and has recently been used for evaluation of intracranial arterial flow. Using a 3T system with optimization of both temporal resolution and k-space subsampling with a combination of parallel imaging and cut-corner acquisition, the clinical assessment of a patient with an arteriovenous malformation was carried out by providing complete intracranial arterial and venous coverage in a scan time of 677 heartbeats.
