Vascular transport analysis based on dynamic CT data for diagnosis of cerebrovascular disease

我们提出了一种新的分析动态CT数据的方法来评估脑血管疾病患者的血流动力学状态。该方法测量了沿大血管线注射造影剂引起的CT图像强度的变化。通过对这些数据的分析，我们可以定量地提取关于血流动力学状态的有用信息。在本研究中，我们开发了动态CT数据处理系统，并将其应用于脑血管疾病患者。

We proposed a new method to analyze dynamic CT data for assessing a hemodynamic status of a patient with cerebrovascular disease. The method measures changes in CT image intensity induced by the injection of a contrast medium along the lines with large vessels. By analyzing these data, we can extract useful information on the hemodynamic status in quantitative fashion. In the present study, we developed the data processing system for the dynamic CT data and applied to the patients with cerebrovascular disease.
