CIRCLE OF WILLIS VARIABILITY AND MIGRAINE

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。 该项目的中心假设是Willis环异常与以下改变相关： 脑血流动力学和有助于偏头痛的易感性和缺血性并发症 偏头痛本项目使用ASL、渡越时间图、高分辨率MRA和fMRI来研究 偏头痛患者Willis环结构变异及相关功能改变 与对照组相比。

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. The central hypothesis of this project is that circle of Willis anomalies correlate with alterations in cerebral hemodynamics and contribute to migraine susceptibility and ischemic complications of migraine. This project uses ASL, transit time mapping, high resolution MRA and fMRI to study the structural variation of Circle of Willis and associated functional changes in migraine patients compared to matched controls.
