DSA的时间-密度曲线分析提供了有用的血流信息。然而，手动选择ROI是耗时的。我们开发了一种自动技术，提供动脉，毛细血管和静脉血管与相应的时间密度曲线。回顾性分析36例单侧颈动脉狭窄患者的临床资料。我们发现，自动分割的毛细血管系统的时间-密度曲线的半高宽是脑循环时间的合适表示。
Time-density curve analysis of DSA provides useful blood flow information. However, manually selecting the ROI is time-consuming. We developed an automatic technique to provide arterial, capillary, and venous vasculatures with corresponding time-density curves. This study retrospectively analyzed the data of 36 patients with unilateral carotid stenosis. We found that the full width at half maximum of the time-density curve for the automatically segmented capillary vasculature is a suitable representation of the cerebral circulation time.
