脑CT灌注成像联合CT血管成像在超急性期脑梗死中的应用

The Application of Brain CT Perfusion Imaging Combined with CT Angiography in the Treatment of Acute Cerebral Infarction

目的调查CT灌注成像(CTPI)联合血管成像(CTA)在超急性期脑梗死中(HCI)的应用效果。方法分别采用CT、CTPI和CTA对23例HCI患者进行检查。对输出的图像进行对比,调查分析最终的病灶大小跟CTPI与CTA的关系。结果被调查的23例脑梗死患者都在发病的6h内进行了就诊。其中CT平扫图像中发现早期表现的仅有6例;CTPI图像中发现灌注异常的有22例;CTA图像中显示异常的有18例。结论在超早期脑梗死的诊断上CTPI联合CTA较CT平扫有明显优势。

Objective To investigate the effect of CT perfusion imaging(CTPI)combined with angiography(CTA)in hyperacute cerebral infarction(HCI).Methods Twenty-three patients with HCI were examined by CT,CTPI and CTA.The output images were compared and the relationship between the final lesion size and CTPI and CTA was investigated.Results Twenty-three patients with cerebral infarction were investigated within 6 hours of onset.Among them,only 6 cases showed early manifestations in CT scan images;22 cases showed perfusion abnormalities in CTPI images;18 cases showed abnormalities in CTA images.Conclusion CTPI combined with CTA has a significant advantage over CT scan in the diagnosis of ultra-early cerebral infarction.
