Enhancement of the brain substance for CT evaluation using inhaled Xenon is confirmed. This technique was applied to the study of the normal and the embolized adolescent baboon. Healthy cerebral tissue enhances symmetrically, while abnormal areas show significantly diminished enhancement. At maximal enhancement, an indication of gross comparative cerebral perfusion to obtained. By obtaining serial CT scans over a 10 minute time interval, the clearance rate of Xenon (cerebral blood flow) may be evaluated. Xenon-enhanced CT enables a visual and numerical analysis of both brain morphology and physiology.
已证实用吸入氙气增强脑实质以进行CT评估的方法可行。该技术应用于正常及栓塞的幼年狒狒的研究。健康脑组织呈对称增强，而异常区域的增强则显著减弱。在最大增强时，可获得大体比较性脑灌注的指标。通过在10分钟时间间隔内进行系列CT扫描，可评估氙气的清除率（脑血流量）。氙气增强CT能够对脑形态和生理进行视觉和数值分析。
