Abstrakt: 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.
