急性缺血性卒中的影像学"不匹配"

Imaging"mismatch"in acute ischemic stroke

急性缺血性卒中存在缺血半暗带及梗死核心,两者体积具有较大差异时即称为"不匹配"。它不仅表现为临床表现与梗死核心的不匹配,也表现为梗死核心与灌注区域的不匹配。神经影像学技术的进步使得这种"不匹配"现象能够通过不同影像学方法,或同一影像学方法的不同序列显示出来,从而为进一步诊疗过程提供更多的指导。

Acute ischemic stroke has ischemic penumbra and actual infarct core,and when there is a bigger difference in the volume of the two,it is called"mismatch".It is not only manifested as a mismatch between the clinical manifestations and the infarct core,but also as a mismatch between the infarct core and the perfusion area.The advancement of neuroimaging technology enables this"mismatch"phenomenon to be manifested through different imaging methods or different sequences of the same imaging method,thereby providing more guidance for the further diagnosis and treatment process.
