Two patients with arteriovenous malformation were studied by position emission tomography, using the steady-state technique with 15O2. In the first patient, who had seizures, preceded by auditory hallucinations, an area of decreased cerebral blood flow and oxygen consumption was shown just behind the malformation. In the second patient, who had repeated attacks of right hemiparesis, an area of decreased blood flow and oxygen metabolism was shown at distance of the malformation. These areas of low flow and metabolism are most probably the result of a vascular steal phenomenon and the origin of the transient neurological symptoms in both patients.
对两名患有动静脉畸形的患者进行了正电子发射断层扫描研究，采用含15O2的稳态技术。第一名患者有癫痫发作，发作前有幻听，在畸形病灶后方显示出脑血流量和氧消耗量减少的区域。第二名患者有反复发作的右半身轻瘫，在距畸形病灶一定距离处显示出血流和氧代谢减少的区域。这些低血流和低代谢区域很可能是血管窃血现象的结果，也是两名患者短暂性神经症状的根源。
