Cerebral Blood Flow Determination Within the First 8 Hours of Cerebral Infarction Using Stable Xenon-Enhanced CT Stroke 20:754-760, Hughes,R.L.,et al, 1989 See this aricle in Pubmed Article Abstract Cerebral blood flow mapping with stable xenon-enhanced computed tomography (Xe/CT)was performed in conjunction with conventional computed tomography (CT)within the first 8 hours after the onset of symptoms in seven patients with cerebral infarction.Six patients had hemispheric infarctions,and one had a progressive brainstem infarction.Three patients with very low(<10 ml/100 g/min)blood flow in an anatomic area appropriate for the neurologic deficit had no clinical improvement by the time of discharge from the hospital;follow-up CT scans of these three patients confirmed infarction in the area of very low blood flow.Three patients with moderate blood flow reductions(15-45 ml/100 g/min)in the appropriate anatomic area had significant clinical improvement from their initial deficits and had normal follow-up CT scans.One patient studied 8 hours after stroke had increased blood flow(hyperemia)in the appropriate anatomic area and made no clinical recovery.
