| 摘 要： | 目的：探讨CT平扫、CT血流灌注成像（CTP）、磁共振弥散加权成像（DWI）及螺旋CT血管造影（CTA）对缺血性脑血管病的比较影像学价值,找出缺血性脑血管病的合理影像检查路径。方法：30例缺血性脑血管病患者经CT、CTA、CTP、DWI检查。结果：30例患者中,12例CT平扫显示责任病灶,27例CTA显示责任血管。DWI与CTP对缺血性脑血管病的敏感性分别为73.3%,83.3%,阳性预测值分别为95.7%,92.6%,两者无显著性差异。结论：CT平扫是常规筛选检查,CTP和DWI是发现脑组织缺血改变的敏感方法,CTA适用于确定责任血管。CTP和DWI、CTA检查可根据病人经济条件及临床表现灵活选择。
