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

这个子项目是许多研究子项目中利用 资源由NIH/NCRR资助的中心拨款提供。子项目和 调查员(PI)可能从NIH的另一个来源获得了主要资金， 并因此可以在其他清晰的条目中表示。列出的机构是 该中心不一定是调查人员的机构。 时间分辨、三维速度编码的磁共振成像(4D Flow)可以获得动态的、多方向的血流数据，最近已被用于评估颅内动脉血流。使用时间分辨率和k空间亚采样优化的3T系统，结合并行成像和切角采集，在677次心跳的扫描时间内提供完整的颅内动脉和静脉覆盖，对1例动静脉畸形患者进行了临床评估。

This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. 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.
