摘要
目的探讨血管性认知功能损害患者脑CT灌注成像特征,分析其与认知功能的相关性。方法 2016-06—2018-06在焦作市第二人民医院住院诊治的缺血性脑卒中患者112例进行蒙特利尔认知评估量表(MoCA)测验,依据测试结果分为认知功能正常者46例和不正常者66例,认知功能不正常者进一步分为血管性非痴呆认知功能损害(vascular cognitive impairmentno-dementia,V-CIND)组48例和血管性痴呆(VaD)组18例,分析各组患者脑CT灌注成像特征,以及与认知功能的相关性。结果本次入组112例脑卒中患者VCI发生率为58.93%。脑血容量(CBV)及脑血流量(CBF)指标3组间比较差异有意义(P<0.05);CBV和CBF与MoCA评分呈正相关(P<0.05),与连线测验完成时间呈负相关(P<0.05)。结论认知障碍患者均存在不同程度的脑血流灌注降低,且随着认知功能进展血流灌注进一步下降,脑计算机断层灌注成像可早期识别VCI,为临床诊治提供依据。
