OBJECTIVE
To assess whether carotid blood flow measurements predict abnormalities in cerebral hemispheric perfusion.
DESIGN
The Quantix/NDTM system was used to measure carotid artery blood flow in nine patients with subarachnoid haemorrhage who underwent CT perfusion scanning.
RESULTS
No significant correlation was found between internal carotid artery blood flow and ipsilateral cerebral hemispheric perfusion (013, p>0.05) but there was a statistically significant correlation between total internal carotid and global cerebral perfusion (0.63, p<0.05).
CONCLUSIONS
This is the first report comparing the Quantix/NDTM system with CT perfusion. Our data do not show a statistically significant correlation between extracranial blood flow and cerebral hemispheric perfusion. This is in contrast to two previous studies where Quantix/NDTM measurements were compared with measurements of cerebral perfusion using the Xenon clearance technique.
目的
评估颈动脉血流测量是否能预测大脑半球灌注异常。
设计
使用Quantix/NDTM系统测量9例蛛网膜下腔出血患者的颈动脉血流，这些患者均接受了CT灌注扫描。
结果
颈内动脉血流与同侧大脑半球灌注之间未发现显著相关性（r = 0.13，p>0.05），但颈内动脉总血流与全脑灌注之间存在统计学显著相关性（r = 0.63，p<0.05）。
结论
这是第一篇将Quantix/NDTM系统与CT灌注进行比较的报告。我们的数据未显示颅外血流与大脑半球灌注之间存在统计学显著相关性。这与之前两项将Quantix/NDTM测量结果与使用氙清除技术测量的脑灌注结果进行比较的研究形成对比。
