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.

这个子项目是许多研究子项目中的一个 由NIH/NCRR资助的中心赠款提供的资源。子项目和 研究者（PI）可能从另一个NIH来源获得了主要资金， 因此可以在其他CRISP条目中表示。所列机构为 研究中心，而研究中心不一定是研究者所在的机构。 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，最近已用于评价颅内动脉血流。使用优化了时间分辨率和k空间子采样的3 T系统，结合并行成像和切角采集，通过在677次心跳的扫描时间内提供完整的颅内动脉和静脉覆盖，对动静脉畸形患者进行了临床评估。
