| 摘 要： | CT脑灌注成像(CTP)可以显示脑血流动力学信息,早期即可显示缺血的梗死灶和缺血性半暗带,预测可以存活的脑组织,对早期诊断和治疗脑梗死及判断预后具有重要价值。随着64层螺旋CT的广泛应用,明显缩短了扫描时间,CT平扫、CTP和CT血管造影(CTangiography,CTA)联合扫描20min内即可完成,而且利用CTA和平扫图像获得三维脑灌注血容量(perfused blood volume,PBV)成像,可以全面显示病灶范围,避免小病灶的漏诊。 |

| Abstract: | CT perfusion(CTP)can provide cerebral hemodynamic information and demonstrate infarct core and ischemic penumbra in acute ischemic stoke.CTP is helpful in diagnosing ischemia,making therapeutic decision and predicting clinical outcome.With the advent of 64-slice CT,the combination of noncontrast-enhanced CT(NECT),CTP,and CT angiography(CTA)can rapidly provide comprehensive information in acute ischemic stroke patients within 20 minutes.3D perfused blood volume calculations are based on CTA and NECT images that cover the whole brain to avoid omitting lesions. |
| Keywords: | Cerebral ischemia Hyperacute Perfusion Tomography X-ray computed |
