摘要
目的应用磁共振弥散(DWI)及灌注成像(PWI)对脑梗死缺血半暗带(IP)判定及其在预后评估的价值。方法对41例符合入组标准的脑梗死患者进行磁共振扫描,分别于入院、发病一、三个月对患者进行神经运动功能评分(NIHSS)。应用DWI及PWI面积值计算IP,结合NIHSS评估IP在脑梗死预后价值。结果 39例患者存在IP,对IP/PWI与NIHSS差值进行相关性分析,两者呈正相关关系,IP/PWI比值越大患者预后越好。结论应用DWI与PWI测量IP及评估脑梗死预后具有一定价值。
Objective Investigate the MR-DWI and PWI were used in ischemic penumbra of cerebral infarction and assess the prognosis.Methods 41 cerebral infarction cases with MRI scaned were inclused,get the NIHSS by Nerve physician at were admitted to hospital,one months and three months of inhospital.Application ？？the area of difference of DWI and PWI,combined with NIHSS to assess the prognostic value of IP in cerebral infarction.Results 39 IP were measured,for IP/PWI and the NIHSS difference correlation analysis,a positive correlation between the two,IP/PWI ratio hinger the prognosis is better.Conclusion DWI and PWI measurement and assessment of cerebral infarction prognosis IP has a certain value.
