详细了解正常脑动脉的血流动力学状况对于更好地了解导致脑血管疾病发生和进展的潜在机制非常重要。血液动力学变量（如壁面剪切应力）的基线值信息对于与病理条件（如脑动脉瘤或动脉狭窄）进行比较是必要的。本研究的目的是比较4D相位对比磁共振和基于图像的计算流体动力学技术确定的正常受试者脑动脉中的血流模式，以评估其一致性并突出其差异。其目的不是验证（或反驳）这两种方法中的任何一种，而是确定预计会出现分歧的区域，并在解释每种方法产生的数据时提供指导。
Detailed knowledge of the hemodynamic conditions in normal cerebral arteries is important for a better understanding of the underlying mechanisms leading to the initiation and progression of cerebrovascular diseases. Information about the baseline values of hemodynamic variables such as wall shear stresses is necessary for comparison to pathological conditions such as in cerebral aneurysms or arterial stenoses. The purpose of this study was to compare the blood flow patterns in cerebral arteries of normal subjects determined by 4D phase-contrast magnetic resonance and image-based computational fluid dynamics techniques in order to assess their consistency and to highlight their differences. The goal was not to validate (or disprove) any of the two methodologies but rather to identify regions where disagreements are to be expected and to provide guidance when interpreting the data produced by each technique.
