【摘 要】目的：对CT灌注成像对烟雾病脑血管重建术后患者血流动力学改变评价效果进行分析。方法：选取我院烟雾病脑血管重建术后患者75例开展本次实验，采取CT灌注成像，统计和记录异常灌注区及双侧相对正常区情况。结果：相比双侧相对正常区，异常灌注区rCBV及rCBF较低，TTP、DLY及MTT较长，之间存在明显差异，具有统计学意义(p<0.05)。结论：CT灌注成像对烟雾病脑血管重建术后患者血流动力学改变评价效果显著。

    Abstract： objective：to .evaluate the effect of CT perfusion imaging on hemodynamic changes in patients with moyamoya disease after cerebral vascular reconstruction. Methods： 75 patients with moyamoya disease after cerebral vascular reconstruction in our hospital were selected to carry out this experiment. CT perfusion imaging was used to count and record the abnormal perfusion area and bilateral relative normal area.Results： compared with the normal area ......
