采用正电子发射计算机断层扫描检测3例儿童烟雾病患者脑血流量、脑氧代谢率（CBF）和cro2，探讨脑电图“重建”现象的机制。过度通气后CBF和cro2均下降。然而，也观察到CBF减少和cro2之间的解离。动脉血气分析显示过度通气时低呼吸和过度通气后缺氧。这些结果清楚地表明，脑电图上的重建不仅是缺血性缺氧的表现，也是烟雾病所特有的缺氧的表现。
The cerebral blood flow and cerebral metabolic rate of oxygen (CBF and CMRO2) of three cases of childhood moyamoya disease were examined by positron-emission-computed tomography for the purpose of investigating the mechanism of the “re-build-up” phenomenon on EEG. Decrease in both CBF and CMRO2were observed following hyperventilation. However, dissociation between the decrease in CBF and CMRO2was also observed. Arterial blood-gas analysis disclosed hypocapnea during hyperventilation and hypoxia following hyperventilation. These results clearly indicate that the re-build-up seen on EEG is the manifestation not only of ischemic hypoxia but also of hypoxic hypoxia characteristically seen in moyamoya disease.
